Description

200829961 IX. Description of the Invention: [Technical Fields of the Invention] The present invention relates to a display device for displaying a personal computer, a television, a mobile phone, etc., a display device for a touch panel such as an eight car, a navigation device, and an ATM; (surface) and plastic case (case), etc., surface materials for display surfaces such as display displays, and high-quality displays and high-quality touch panels having surface materials for the display. &

[Prior Art] In such a display, if light from the outside is not scattered and reflected on the surface (display surface), since the image is moved in, the image inside becomes extremely difficult to be seen, and thus the display is The surface is provided with an anti-glare layer for external light scattering. , ..., two #丁久于指的眼 contact with the surface of the monitor ΐ ^ ^ ^ surface will adhere to the body from the ingredients (especially lipid) grain "track"). Refers to: 3 traces of skin traces (hereinafter, simply referred to as "therefore, the visibility of the damage-preventing image is already present." For example, the countermeasure for revealing the attachment of the trace to the surface of the display is mentioned and The anti-glare layer formed on the transparent substrate (transparent film) is formed on the transparent substrate (transparent film), and the anti-glare layer of the anti-glare layer of the patent document (for example, the reference compound, and the anti-glare property of the anti-staining property The layer contains a fluoride-modified chelate angle of more than 43. The oil ester (triaCetin) is attached to the surface of the anti-glare layer. Patent Document 1 and Page 4) 曰本特开2000-194272 (Page 2 due to patent The anti-fouling layer of the document fingerprint trace has a low surface free energy, so it has less, and has the advantage of easily wiping off the fingerprint of the attached fingerprint 6 200829961. However, since the anti-glare layer contains a fluorine-modified compound, The contact angle of triacetin relative to the surface of the anti-glare layer exceeds 43 degrees, and the lipid component from the body is likely to form minute droplets attached to the anti-glare layer. The tiny droplets of the lipid component from the body cause reflexes of light. So that on the surface of the display Trace pattern becomes conspicuous. Therefore, Patent Document 1 can not improve the display of video display so-called "low visibility legibility" of the problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide a Nanzhao-quality surface that has both an anti-glare function and a function that makes fingerprint marks attached to a surface less conspicuous, and which can improve the visibility of the display. The material 'and the high-quality display and the high-quality touch panel with the surface material. The inventors of the present invention have noticed that the fingerprint mark attached to the surface of the display is composed of minute droplets of the lipid component from the body, and it is confirmed that the fingerprint trace which can be recognized by the eye is light to the minute droplet thereof. Caused by chaotic reflection. . Therefore, the inventors of the present invention have carried out another angle of thinking. If the lipid component from the body is not formed into a micro-liquid sputum, the surface of the human body is found to be inconspicuous. . The invention of the present invention enables the concave and convex facet formed on the surface from the body to be reduced from the amount of the body, and which is composed of the aforementioned surface, the surface of the body having a high affinity Absorption, so that the scallop can be hunted by the capillary phenomenon as the haze value of the surface material, the eye, and by controlling the effect that is difficult to conspicuous, so the end = the fingerprint trace of the surface 7 200829961 The first of the present invention Remove the surface material from the rabbit. The 丄 丄 种 种 丄 丄 丄 丄 丄 丄 丄 丄 丄 丄 ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ 、 、 、 、 、 、 、 、 、 、 、 、 The above-mentioned antiglare layer has a surface energy of a glare layer on all surfaces of 37 to 30 mm, and the above-mentioned material has a haze value of 3 to 50%. Two: Two? : Appropriate surface The average spacing of the surface irregularities is 2f). In the composition, the good anti-glare property caused by the anti-glare layer is used: and it is set to realize the recognizability of the light diffuser. 4, === enamel display Fu / m, the anti-glare layer is good for the surface of the moon after the formation of 3 〇 to 70. In addition, because of the obvious ambiguity, the affinity of the ingredients of 艮, will change, and can be continued to 3 to * I S U traitors Α j j difficult M meal: pay attention. Therefore, the machine and the two-component agent = real two: the upper middle == the micro-particles are dispersed in the sticky 10 handsome, the average particle size of the fine particles is (U to the material. In this configuration, 3 is made up; 55.30, the smaller average particle size, and the particle control I, so can be achieved without the formation of excessive concavities and convexities =: less surface glare and prevent exposure and can be used as a mussel In the above, the above function is not a light scattering layer in the middle layer, and the second aspect can be improved in the surface of the display material of the material, and the display and the touch panel having a high image height can be obtained by using ^^^ 8 200829961. The best way to reinvent the invention is as follows: The use of "Second-heartedness in the present specification" is difficult to remove the lipid component from the body, and it is difficult to remove the lipid component from the body.

The high-quality display of the present embodiment is designed to be placed on the surface of a display such as a panel or a liquid crystal panel by using a surface material for a user's display or a surface material. Displaying the crying: The surface material is provided on the transparent substrate directly or via the functional layer. The average interval of the unevenness on the surface of the anti-glare layer is set to 2 〇 to 300 μm, the surface energy is set to 3 〇 to 7 〇 mN/m, and the surface material has a duty value of 3 to 50%. By setting the average interval of the concavities and convexities on the surface of the anti-glare layer to 20 to 30 μm, the reflected light can be scattered to exhibit anti-glare properties. Furthermore, by setting the surface energy of the surface of the anti-glare layer to 3 〇 to 70 mN/m', the affinity of the anti-glare layer to the lipid component from the body can be improved, and the lipid component from the body can be easily introduced into the anti-glare. The concave portion of the surface of the layer is not easy to show fingerprint marks. Further, by adjusting the haze value to 3 to 50% and adjusting the ambiguity, the lipid component from the body on the surface of the anti-glare layer can be made more conspicuous. Therefore, the visibility of the high-definition display can be improved. Although the above anti-glare layer is usually directly disposed on the transparent substrate, at least one functional layer may be disposed between the transparent substrate and the anti-glare layer. Further, on the antiglare layer, a coating layer having affinity for a lipid component derived from the body such as a fingerprint mark can be formed. Moreover, in the surface material for display 9 200829961 = lunar surface (in the two main faces of the transparent substrate, the main surface of the upper layer side of the core (4) layer machine *) is provided with an adhesive layer, and the surface material is pasted by the acoustic coating of the adhesive. It is used before the test of the material. Double X Drink Day Panel w In this article, for high-quality display, high book means high-quality display with high image resolution. That is, the image (image) is more dense, and the pixel density is increased. In the conventional display, although the pixel density is about 5 〇 to just ^ = :, dots, dots per inch) 'but at high Tantalum display (the twist is about 100 to 300 dpi. Susan is on the high-quality display, if it has a conventional anti-glare film (surface material for display), the light of the high-quality display (reflection The ship's character such as text or lines will be significantly damaged. The occurrence of the ray is related to the size of the anti-glare layer. The anti-glare layer is larger than the opening of the black matrix of each pixel boundary of the display. The effect is that the image light is scattered at the unevenness on the surface of the anti-glare layer. This is also called flicker phenomenon. In this specification, "shining" is a phenomenon caused by light from inside the display, and the fish is not external. The glare caused by the illumination is different. ',,, and the components of the surface material for the display are described next. As the transparent substrate, a transparent resin film, a transparent resin sheet, a transparent glass plate, or the like can be used. There is no egg off. Specifically, the tree material may be a poly(fluorenyl)acrylic resin, a poly(methyl acrylonitrile resin, a polystyrene resin, a polysilicon resin, a polycentric wind, a fat, a poly-based resin, or the like. Polymethyl pentane resin, triethyl sulphate, quasi-tin (TAC) resin, polyparaphenylene hydrazine acetate (ρΕΤ) resin, polyamino acid brewing resin, regenerated cellulose resin,二乙酿200829961 素素基丁乱 Cellulose tree wax, polyester tree: Erkun ternary copolymer resin, polycarbonate 1 tree month, poly-resin resin, polyvinyl chloride _ resin, 3 糸 ^ , polyvinyl alcohol-based resin, nylon-based resin, polyethylene-based, polypropylene-based pure fat, aramid-based tree Ξ=1 (: base) acrylic acid wax, polystyrene

It is preferred that the iFTull-dimensional (TAC) resin or the polyethylene terephthalate is a polyglycolic acid-based resin. A polarizing plate is used as the machine. This layer w' usually uses a triacetyl cellulose (tac) resin. The thickness of the transparent substrate is usually 10 to 5000 μm, and it is more preferable to use = _μιη. The thickness is less than 1 ,, the workability is poor, and the strength of the transparent substrate tends to decrease. Further, when the thickness exceeds 5000 μm, it is only unnecessary thickening, which is meaningless. ‘... Next, the anti-glare layer will be explained. The anti-glare layer has a layer on the surface thereof, and the layer which exhibits the function of achieving anti-glare property by the light reflection and scattering (surface scattering property) of the unevenness. In order to achieve surface scattering, it can be achieved by controlling the concave and convex structure of the surface of the antiglare layer. Regarding the uneven structure of the surface of the anti-glare layer, the average interval (Sm) of the unevenness defined by jIS B060M994 must be 2 Å to 300 μm, preferably 30 to 2 (% m is preferable, and 30 to ioopm is particularly preferable. Sm is 20 to 300μηη, which can suppress the glare when the surface material is set on the high-density display, ensuring the display's good identifiability. In addition, the right Sm $ is reduced to 30 to ΙΟΟμιη to suppress the flash surface. Preferably, as shown in the following examples, when the Sm is 230 μm or 150 μm (Examples 1 and 2), when Sm 200829961 is 55 to 90 μm (Examples 3 to 8) The eye-catching difficulty of the fingerprint mark and the easy-to-identifyness of the display are excellent, and the glare can be suppressed particularly effectively. Further, the surface of the anti-glare layer is equal to the average roughness (Ra) according to JIS Β 0601-1994. 3 μπι or less is preferable, and the ten-point average roughness (Rz) is preferably 2·0 μπι or less. It is more preferable that the Ra is 〇〇1 to 〇2 and Rz is from 0.11 to 1.5 μm. It is preferable that the Ra is 〇〇5 to 〇15, and Rz is 0.5 to 1.3 μm, by using an anti-glare layer. When the surface material is placed on a high-quality display, it will not shine when it is placed on a high-quality display, and the display can be easily recognized. The blaze is a lens due to the unevenness of the surface of the anti-glare layer. The size of the lens is related to the value of Sm. When it is within the above range, it is possible to suppress the flash surface when it is placed on the surface of a so-called high-quality display. If the relationship with the pixel is specified in the cancer, Sm is 1 It is preferably in the range of 1 to 80% of the pixel size, more preferably in the range of 1 to 65 Å/〇, and most preferably in the range of 1 to 50%. Light measured at an angle of 60 degrees • Sloss (hereinafter referred to as 60-degree gloss value) is preferably 1% or less, preferably 90% or less, and 1% to 90%. Preferably, it is preferably 5〇 to 90%. The '60 degree gloss value is measured according to jig K71〇5, so that the light from the standard light source is irradiated with the sample at a predetermined incident angle, and the positive reflected light is measured by the light receiver. When the reference surface is a smooth glass surface, the haze value is set to 1 (eight)%. The gloss value exceeds 100%. The surface material, the anti-glare property is insufficient, and the anti-glare effect (the glare-reducing effect) is insufficient when the surface material is placed on the surface of the display. The gloss value is also related to the uneven structure of the surface of the anti-glare layer. The gloss value is 1% or less, which means that it is denser than the uneven structure when the value is exceeded. 12 200829961 Since the unevenness is formed on the surface of the anti-glare layer as described above, the fat f component from the body such as fingerprint marks = ^ The surface energy of the glare layer must be 30 to 70 mN/m, which is 35 to, still, preferably, 37 k vr/ a $ mN/m is set to 30 ^. It is presumed that the surface energy is 30 to 70 mN/m. The anti-glare layer can be raised for the body from the body and the sex will quickly come from the body's lipids:

The fingerprint traces produced by the branch are difficult to identify 7: When the energy === 30mN/m or less, the lipid component from the body becomes easy to form & small droplets and light reflection, and the hair generated based on the surface unevenness 2 Phenomenon 'The absorption of lipid components from the body has also become difficult, and the susceptibility of the two images has become worse. Furthermore, it is over 7. On the second day of the day, it will become difficult to form such an anti-glare layer. Although the method of determining the surface energy is not particularly limited, any method can be employed, but it is preferably measured in accordance with the "wet tensile test method" according to J. K6768. The antiglare layer is not particularly limited as long as it has such surface energy, and any resin (binder resin) can be used, but it is usually formed by using a transparent resin as a constituent component. As the transparent resin, for example, an active energy ray-hardening resin, a thermosetting type, a enamel, a thermoplastic resin or the like can be used. Among them, from the viewpoint of productivity and physical properties, it is preferred to use an active energy ray-curable resin or a thermoplastic resin. ^ When using an active energy ray-curable resin, it is necessary to use a polymerizable component as its constituent component. With respect to such a polymerizable component, an oligomer having a vinyl group or a (meth)acryl fluorenyl group (hereinafter referred to as a polymerizable oligomer) and having ethylene can be obtained from a single B-b monomer, a s-g monomer, a vinyl group or a (meth) acrylonitrile group. Among the polymers of the (meth)acrylonitrile group (hereinafter referred to as polymerizable polymer), 13 200829961 or two types are used: for use. In addition, if necessary, it can be used as a polymerization initiator, a vinyl-free or (meth)propene-based compound (the following % is a non-polymerizable oligomer), and *containing an ethyl group (a base). An acrylonitrile-based polymer (hereinafter referred to as a non-polymerizable polymer), an additive such as earth, gold, a milk, a surfactant, a diluent solvent, a photosensitizer, an ultraviolet absorber, an infrared absorber, or an antioxidant. Borrow = energy: = oxygen: dimerized broad oligomer or non-polymerizable polymer (this two are collectively referred to as "each oligomer or each polymer"). To raise the monofunctional monomer of the polymer or each polymer, /, it is necessary to consider the type and amount of the early S layer. In the amount of the mouth i, the monofunctional monomer can form a surface energy of 30 to 70 mN/m, and is not particularly limited. It is only monofunctional and simple, and the surface energy of 4= to: 0mN/m is more than 10% by mass in the difficult component, and it is preferably 3:! When the quality is 50, it is the best. The ratio is less than 3% by mass, and the fracture layer is applied to the lipid component of the body. For the body part, the ϋδ initiator is used as the 'polymerization component 100. It is preferably from 0. 01 to 20 parts by mass. The addition ratio is not 200829961 j 0. 〇1 Berry injury % The film obtained from the composition for forming an antiglare layer is hardly completely cured by 1 and hardening is insufficient, so it is less. On the other hand, when the addition ratio exceeds 2 parts by mass, a sufficiently hardened coating film can be served, but a better effect cannot be expected, and it is not necessary to use such a large amount of waste. There is no particular limitation on the kind of the polymerization initiator such as a photodecomposition type or a thermal decomposition type to be used. Further, when a combination of the above monofunctional monomer and a polyfunctional monomer is added with a j oligomer or a polymer, the axis is 30 to 7 Å/m in energy, and the monofunctional group is monofunctional, and more. . The total amount of the "filament or each polymer" is usually 1 or more, more preferably 30% by mass or more, and %% or more. /^ ' is preferably 75 mass% or more. If the ratio is less than 30%, the anti-glare layer has a poor affinity for the lipid component derived from the body. When the iUlt is 10% by mass, the anti-glare layer depends on the fatness of the body from the ',, and affinity. Further, the amount of addition of the non-polymerizable oligomer or the non-polymerization is 'four' to the polymerizable component i (8) parts by mass and the second = hanging mass parts or less, and preferably 10 to 80 parts by mass. When the amount is from 1 G to 80 f, the strength of the active energy ray-curable resin film from the lipid component of the body is excellent. When the plastic resin is used as a composition for forming an anti-glare layer, the anti-glare component must be a polymer obtained by polymerizing the above-mentioned active energy ray containing an early functional monomer, or a non-t. The functional group polymer 'in addition, a boundary, a diluent solvent, a stabilizer, a UV absorber, an infrared absorber or an antioxidant may be added as needed. Regarding the monofunctional monomer, there is no particular limitation as long as the condition of "the surface of the resin which can form a surface energy of 30 15 200829961 to TOm ^ m" is satisfied. A monofunctional monomer capable of effectively increasing the surface energy is preferably, for example, the following monofunctional monomer.

However, the proportion of the active energy ray-curable resin or the thermoplastic resin is preferably 30% by mass or more, and preferably 5 Å by mass or more. More preferably, it is preferably 75 mass% or more. If the ratio is less than 5% by mass, the _ glare layer exhibits a tendency to fail to exert a desired surface energy on the surface thereof. The polyfunctional monomer may be an esterified product of a polyhydric alcohol and (mercapto)acrylic acid, or a polyfunctional polymerizable compound containing two or more (meth)acrylonyl groups such as acryl vinegar modified with an amino formic acid.

The oligomer having a vinyl group or a (meth) acrylonitrile group may, for example, be an oligomer obtained by adding a vinyl group or a (meth) acrylonitrile group to the above oligomer. The polymer which does not contain a vinyl group or a (meth) acrylonitrile group may, for example, be a polymer type of the above-mentioned oligomer which does not contain a vinyl group or a (meth) fluorenyl group.

For example, it may be blocked by alkyl esterification or alkyl etherification or the like. Further, the chain may be bonded to a ruthenium atom via a dimethylene group or a triadenylene group, but is not limited thereto. The polyoxyalkylene-based compound is preferably polydimethylene-oxygen-modified polyether-modified, and examples of the commercially available product include "BYK-306", "BYK330", "BYK-341", and " BYK-344", "BYK-307", "BYK333" (BYK company) and "VXL-4930" (made by Vianova Resins). When the composition for an antiglare layer composed of an active energy ray-curable resin* or a thermoplastic resin is applied, the solvent is used to adjust the viscosity of the coating liquid, and it is not necessary to be non-polymerizable. Special restrictions. The diluent solvent may, for example, be toluene, xylene, ethyl acetate, 21 200829961 propylene acetate, butyl acetate, methoxyethanol (original methyl celhisolve, abbreviated as 2 methoxy ethanol), ethoxyethanol, ethoxyethanol Acetate, decyl alcohol, ethanol, isopropanol, butanol, acetone, mercaptoethyl ketone, decyl isobutyl ketone, cyclohexanone, hexane, gamma, simmer, simmer, ten Burning, propylene fine, fermented early scales or 3-methoxybutanol.

As the photosensitizer, known compounds for the above polymerization initiators such as tributylamine, triethylamine, polyethylene imine, poly-n-butylphosphine, p-dimethylamino group can be used. A benzoic acid ethyl ester or a tertiary amine such as p-dimethyl benzoic acid isoamyl ester. Further, in the active energy ray-curable resin or the thermoplastic resin, the proportion of fluorine atoms is preferably 5% by mass or less, more preferably 〇〇1% by mass or less, and most preferably not contained at all. . In other words, the active ray-ray hardening resin or the thermoplastic resin is composed of atoms other than fluorine atoms or 99.95% by mass of atoms other than the mouse atom, and is preferably composed of 99.99% by mass or more. For better. ^ When the ratio of atoms exceeds 0. 05%, since the fluorine atom is a low-surface free energy component, there is a tendency for the lipids from the body to form a micro-money drop on the outermost surface of the surface material, so that the trace becomes easy to be conspicuous. After the fingerprint trace is attached, the visibility of the (4) image is reduced, so it is not going. In the resin forming the antiglare layer, in order to make it adhere to the surface, the lipid component of the body is more difficult to be conspicuous, and it is preferable to contain gold (fine particles). Regarding the type of metal oxide, although various kinds are not special _, (four) ❹ 邦 邦 ) ) ) 、 、 f f f f f f f f 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉 蓉These metal oxides may suitably be used in one or two or more kinds of 22 200829961. The form of the metal oxide to be added is not particularly limited, and is preferably in the form of a powder or a sol.

The average particle diameter of the metal oxide is not particularly limited, and in view of the dispersibility of the metal oxide and the transparency of the film, it is preferably 1 to 150 nm, more preferably uonm. By setting the average particle diameter of the metal oxide to a preferred range, the affinity between the component and the moon mussel component from the body can be improved, and thus the fingerprint trace attached thereto is less likely to be conspicuous. On the other hand, when the average particle size and inm of the metal oxide are difficult to manufacture and obtain, and the fingerprint trace caused by the lipid component from the body adhering to the surface of the film becomes conspicuous, it is not preferable. On the other hand, when it exceeds 200 nm, the transparency of the metal oxide film and the film will be lowered. The upper 逖i is a private group for the formation of the anti-glare layer:: the: square, the dispersion stability of the composition or the adhesion: the nature of the lowering of the metal oxide to pre-disperse in the organic It is preferred to use it in the form of an organosol. Further, in order to improve the adhesion of the metal oxide fine particles, the adhesion between the metal oxide and the surface of the compound, the metal oxide and the surface may be modified with various coupling agents or the like in advance. The various coupling agents may be, for example, an organic silk-substituted wei compound m, a metal-sintered oxide, and the organic acid "with a compounding =, the metal oxidizing and recombining component oxide 2 is more preferably in a mass 〇/〇. γ~7π μ 5 shell / 1 〇 is preferable, and when it is 20 to 8 〇 mass ° / 〇, the amount of adhesion to the product is preferably the best. The ratio is less than 5 from the surface of the body-derived lipid The composition caused by 23 200829961 = 5 pattern ^! difficult ^ conspicuous function is reduced. On the other hand, the ratio of the super-energy hybrid ray hardening type tree 1 film will not be sufficient strength, so it is not good.

Further, the plastic resin used for the composition for forming an antiglare layer has a resin surface energy of 30 to 70 mN/m, and there is no limitation. It is possible to use a polymer obtained by polymerizing a monofunctional monomer used in the above active energy ray hardening type or a polymer having a non-ruthenium functional group as a main component. Depending on other needs, additives such as agents, stabilizers, UV absorbers (4), infrared absorption = oxidation inhibitors. #Plastic resin, the type of work or the above may be used. When two or more types are used, the ratio may be arbitrarily set = "additives added depending on other needs", and there is no problem in use in the normal use range. When the thermosetting type tree is used in the antiglare layered composition, the condition that the surface energy is 3 to 7 〇 mN/m of the resin surface can be obtained, and there is no particular limitation. As the thermosetting resin, a resin, a urea resin, a diene (tetra) phthalate resin, a trimeric amine tree, a trisamine resin, an unsaturated polyester resin, a polyurethane resin, an epoxy resin can be used. Resin, lanthanum alkanoate, = melamine _ urea co-condensation resin, sec-resin or poly- oxy-fired resin. When one or two or more kinds of these thermosetting resins are used, when two or more types are used in combination, the ratio may be arbitrarily determined. Additives such as a polymerization initiator, a metal oxide, a surfactant, a diluent solvent, a stabilizer, an ultraviolet absorber, an infrared absorber, or an antioxidant may be added to the thermosetting resin as needed. The method of applying the composition for forming an antiglare layer to a transparent substrate may be a roll coating method, a spin coating method, a dip coating method, a brush coating method, a spray coating method, a bar coating method, a knife coating method, or a mold. Head coating method (die 24 200829961 coating), gravure coating method, curtain flow coating method, reverse coating method, conformal coating method or chamfer coating method (c〇mma c〇ating). At the time of coating, if it is desired to improve the interlayer adhesion as needed, any pretreatment such as corona discharge may be applied to the surface of the layer in advance.

The active energy source used for the hardening of the active energy ray-curable resin may be a radiation source such as a high pressure mercury lamp, a halogen lamp, a xenon lamp, a laser, an electron beam accelerator or a radioactive element. The amount of irradiation of the energy source is preferably 50 to 500 〇mj/cm2 or more, based on the cumulative light amount of the ultraviolet wavelength of 365 nm. When the amount of irradiation is not reached, the hardening of the composition for forming an antiglare layer will not be filled, so it is not preferable. When it exceeds 5 〇〇〇 mJ/cm2, the active energy ray-curable resin tends to exhibit coloration, which is not preferable. Further, it is preferable that the antiglare layer is structurally selected in such a manner that the adhesion to the adjacent layer can be improved. Therefore, it is preferred to select a resin which has affinity with the resin forming the adjacent (four). That is, a polymer 4 having affinity with the above-mentioned active energy ray-curable resin or thermoplastic resin, and a polymer having affinity with the layer of the above active energy ray-curable resin or thermoplastic resin may be selected. A fragmented copolymer such as a segment polymer or a graft copolymer. The method of forming the unevenness on the recording surface of the enamel layer can be appropriately selected from the well-known one, and there is no special preference, and it can be, for example, a method of adding a glare layer of a resin material to the granules, or a method corresponding to the desired concave. ίThe original version of the negative image structure (such as embossing (_-)), #. The method of transferring the frequency is not limited, and may be, for example, a transfer of a puller, a transfer of a sheet, or a transfer of a film. r. In the method of adding microparticles, inorganic particles or plastic pellets (tree sapphire particles) can be used as microparticles. However, the adjustment of the difference between the vortex and the refractive index of the transparent resin 25 200829961 is necessary, and the refraction can be selected from the desired Rate = plastic pellets are preferred. The plastic material f can be a vinyl chloride dilute 1 base) acrylic resin, an acrylic-styrene copolymer, a lyon resin, a melamine resin, a polyacetate resin, and the like. X, the average particle diameter of these fine particles is preferably, and more preferably 〇.5~_. The average particle diameter is not sufficient, and the anti-glare property tends to be insufficient, and if it exceeds 1 〇μιη,

〇1 咖) becomes too high 'has a tendency to damage and transparency. The fine particles can be used as fine particles for a light scattering layer to be described later. The amount of the fine particles added is preferably from 5 to 30% by mass, more preferably from 2 to 25% by mass, based on the transparent resin, and is from 3 to 2. The mass % is more preferably 5 to 15% by mass. When the amount of the fine particles added is not more than 5% by mass, sufficient antiglare property cannot be obtained, and it is difficult to form f to absorb the unevenness of the lipid component derived from the body by capillary action. When the amount of the fine particles added exceeds 3% by mass, the haze 2 becomes too high, and the surface material provided on the surface of the display exhibits whitening and image recognition. Then, by a method of forming an antiglare layer by transfer, for example, a composition for forming an antiglare layer to which a transparent resin or the above fine particles is added can be used. Specifically, in the case of the active energy ray-curable resin, the composition for forming an anti-glare layer is applied onto the original plate, and if necessary, pre-curing by an active energy ray until the degree of uneven transfer can be achieved. Soft or thermoplastic. Then, the original plate is embossed on a transparent substrate, and the original plate is removed, or the active energy ray is irradiated and cured as it is without removing the original plate. Furthermore, the stamping may be heated as needed. Further, in the case of the thermoplastic resin, after the composition for forming an antiglare layer is applied and dried, the formed film is pressed at a temperature higher than the softening point of 26 200829961 to be transferred. Examples of the original plate may be, for example, a forming film, a forming roll, or a flat plate die for a forming press, and a commercially available AG (antiglare) film may be used as the forming film.

The thickness of the anti-glare layer may be '0.1 to 1000 μm even if it is larger than the desired height difference, and it is preferable to use 〇·1 to ΙΟΟμηη. When the thickness is thinner than μ 1 μm, it becomes difficult to form a desired degree of unevenness, and when it exceeds 1 〇〇〇 JLim, it means that it is not necessary and is thick. The anti-glare layer designed to correspond to high image quality can prevent flicker and white matter from being reduced in contrast, so it is preferable. The scintillation can be solved by optimizing the surface unevenness as described above. Also, the white mist can be solved by the internal haze value. As described above, surface scattering and internal scattering caused by surface irregularities must be balanced. Further, in order to achieve the above internal scattering property, it is preferred to use fine particles having a particle size smaller than that of the antiglare layer film, and to fill the inside of the film. ^ Use the haze value as its indicator. The haze value (fog price, haze) of the surface material for a high-quality display is measured in accordance with JIS K7136, which is the value of the scattering light transmittance divided by the total light transmittance, which is expressed as a percentage. The haze value is 3 to 50%, preferably 3 to 30%, more preferably 3 to 25%, and most preferably 3 to 2%. When the haze value is less than 3%, the anti-glare effect is insufficient, and when the surface material is disposed on the surface of the display, the effect of preventing the irradiation is insufficient. In the meantime, it is not appropriate because the display is white when the contrast is lowered or placed on the display surface. ~豕% Next, the coating layer provided on the antiglare layer will be described. Since the fingerprint trace is a affinitive layer with a lipid component derived from the body (i.e., the oil layer is the main coating layer as a good affinity for the lipid component from the body). The surface energy of the oil coating layer for the affinity of the lipid component from the body must be the same as the above-mentioned anti-glare layer & '4 ice land horse 30~70 27 200829961 mN/m. Furthermore, in order to be able to treat the fat from the body: the proportion of the fluorine atom in the resin is 〇〇5 quality " :=: and 0.01 mass % or less is more preferable, and the final == 4. That is, the coating layer is formed. The resin is preferably composed of an atom other than a gas atom, or an atom other than a fluorine atom, preferably 999 or more, and is preferably a fluorine atom.

For better. In addition, the component forming the coating layer can be selected as a component of the second layer. The forming method can also be suitably used in the form of a shape, and the thickness of the layer is such that the thickness of the coating layer is not the degree of unevenness, that is, the cavity is removed, and the soil is removed. W~300nm is the best. When f is less than Inm, there is a tendency that it cannot be uniformly applied. On the other hand, if the coating layer fails to follow the two convexities: skin, it is better to reduce the "features of fingerprints that are difficult to conspicuous == but" to apply to the uneven surface of the anti-glare layer; It is considered to have the above-mentioned film thickness. In order to improve the adhesion of the coating layer to the (four) layer, the adhesion-curable resin has a carboxyl group or a viewpoint of having a high functionality of a mercapto group, a mercapto group or an epoxy group; = monomer with or based on, such as (methyl, = acid ester, fumarate, etc.. 1 specific examples of thiol or secret monomers, such as (methyl) acetoacetate, (Meth)acrylic acid _2•hydroxypropyl ride, i-fine rider (10) base _3_phenoxy vinegar, 2-(tetra)decyloxyethyl _ lyl ethyl decanoic acid, penta 28 200829961醯 醯 乙基 乙基 乙基 乙基 、 、 OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP OP Oxygen §2_8, total=Chemical Co., Ltd.

Epoxy Ester 8〇MFA, Kyoeisha Chemical Co., Ltd. = Epoxy Ester 3000A, Co., Ltd., Oxygen Ester 3〇〇2A, Acetyl Oxime Ethyl decanoic acid, NK ester CBX-0 manufactured by Shin-Nakamura Chemical Industry Co., Ltd., NK ester CBX-1N manufactured by Shin-Nakamura Chemical Industry Co., Ltd. carboxy or hydroxyl group in active energy ray-curable resin The content of the monomer is preferably 20% by mass, more preferably 3 to 10% by mass, and particularly preferably 0 to 55% by mass. When the content is less than 0.1% by mass, the content cannot be made. The adhesion of the coating layer to the antiglare layer is sufficiently improved, so it is not good. On the other hand' When it is 20% by mass, the coating layer has an effect of not being able to obtain a blending content in terms of the adhesion of the antiglare layer, and in addition to waste, the physical properties of the antiglare layer are also lowered. Then, the transparent layer is provided. The functional layer between the material and the anti-glare layer is described. For the surface material of the display, one layer or a plurality of layers can be layered between the transparent substrate and the anti-glare layer as needed. Such a functional layer can be, for example, light scattering. Layer, polarizing plate, ultraviolet absorbing layer, infrared absorbing layer, shot preventing layer, soft (impact resistant) layer, hard shell layer, conductive layer, ^ electric stop layer, heat insulation layer, reflective layer, undercoat layer, etc. In the case where the functional layer is used as the light scattering layer, when the total value of the haze values of the two layers of the anti-glare layer and the optical layer is taken as the haze value, the haze value of the light dispersion/layer is caused (the anti-glare layer is formed on the upper portion). The former haze value is preferably 50% or less with respect to the haze value (full haze value) after the anti-glare layer. When the ratio of the degree exceeds 50%, the image of the display is slightly white, and the contrast is lowered, so it is not good. The light-scattering layer scatters light from the display in the surface material in the surface material, thereby realizing the function of increasing the ratio of the rays in the normal direction of the anti-glare layer in the anti-glare layer in the normal direction of the anti-glare layer. In order to achieve this function, the light-scattering layer disperses the fine particles (translucent fine particles) in the transparent resin. From the viewpoint of maintaining the transparency of the light-scattering layer, the difference between the transparent resin and the light-folding of the fine particles is (10) For better, but also from ^

In the sense of scattering, the average particle diameter of the fine particles is preferably 〇. If the difference in refractive index is less than ,1, in order to exhibit the effect of light scattering, it is necessary to add a large number of light-transmitting fine particles, and the adhesion between the light-scattering layer and the transparent material or the light-scattering layer and the anti-glare layer is lowered. Further, when the layer is formed, the coating suitability of the two materials for forming a light-scattering layer containing a large amount of light-transmitting fine particles is lowered, and as a result, it is difficult to form light dispersion uniformly, and h is opposite, and if the difference in refractive index exceeds 〇· 5, the transparency is reduced, the image sharpness and contrast are reduced when the surface material is applied to the display, and the average particle diameter of the right side is less than μ1μηη, and the light scattering layer is formed when the light scattering layer 30 200829961 is formed. In the composition, the fine-particles of the permeable particles are easily aggregated. The coating suitability of the light-scattering layer forming group is lowered, and as a result, it is difficult to uniformly form the light-scattering layer. Conversely, if the average particle size exceeds 7.5 μΐ, the flicker starts to occur. Poor. The thickness of light scattering ^ is usually 0·1~1000μιη, and it is better to use it as the best: 0.1~100 qing is better. When the thickness is less than 〇_, the light scattering effect is insufficient, more than 1 〇 When scattering effect becomes excessive 〇μιη

The sharpness of the image is reduced, so it is not good. Zhang Bei does not W

In the case where a polarizing film is used as the functional layer, an anti-glare polarizing film can be used. Further, in the liquid crystal display, although the term of the polarizing plate is used repeatedly, the actual condition 'is a film having a large thickness, or a sheet-like state' may also be referred to as a polarizing film herein. The polarizing film has a sandwich structure in which a polarizer is sandwiched between two transparent sheets (usually TAC films), and a polarizing film is a film obtained by adding iodine or a dye to a polyvinyl alcohol (PVA) film and extending the film. ,. In addition to polyethylene lysate, polyvinyl acetal film, polyvinyl acetal _, ethylene acetonitrile vinegar is used as a polarizer (4). Therefore, in the production, the transparent film of the polarizing film can be used as a transparent substrate, and the light scattering of the reed, the antiglare layer, and the like can be laminated, and the various layers of the various layers described above can be formed as needed to produce the function. Surface material for displays. θ , the functional layer can be formed using an inorganic substance, an organic substance or a mixture of the same. The thickness is preferably 〇.〇〇5~1〇〇μιη. Further, the formation method of the functional layer is not limited, and a dry coating method (4) (7) or a wet coating method can be used. The functional layer is preferably provided with a function of improving hard production, capital, and scratch resistance. Further, for example, in order to improve the scratch resistance, there is a method of improving the hardness of the functional layer between the transparent bases, and a material for forming the functional layer by the soft layering of the layer 31 200829961, and is not particularly limited. The effect of the present invention, that is, an organic substance, or a mixture thereof can be used. For example, A knows. For example, a hard coat may be used, and two may be used in order to increase the hardness (for example, a hard crosslinkable hardenable monomer is preferably added by adding a monomer. Examples of the monomer may be exemplified. Preferably, it is a hardening acid or a tetraethoxy oxetane or the like, or an oxime (meth) propylene, a polyfunctional (meth) acrylate, an alcohol hexaacrylate, a tetra Methyl hydroxymethyl ketone J cattle one season pentaerythritol vinegar), tetrakis (tetra) A; methacrylic acid vinegar (tetrapentyl pentaerythritol), :, two It _ vinegar (pentaerythritol triacrylate acrylamide propylene f: acrylic vinegar, π The hexylene glycol diacrylic acid alcohol derivative is also a polyfunctional acid ester such as propylene glycol, oxy-2_pyridyloxy)hexanol. , 浚 ethylene glycol diacrylate, or polyurethane acrylate • 曰:. Further, as the inorganic material, ultrafine particles such as vermiculite gel can be used. (4) ^ and 'Settings on the surface of the display silk material will be attached to the surface of the display and the money. Adhesive layer of the coating agent layer, such as acrylic adhesive, rubber adhesive or linalone, but from the viewpoint of transparency, it is better to adhere to acrylic acid, and then From the viewpoint of the peelability, the anthrone-based adhesive i is again. Among these adhesives, in addition to the adhesive polymer component, a plasticizer or a tackifying component may be contained, but it is preferred to carry out the amount in such a manner that transparency is not impaired. The adhesive which is mainly composed of an acrylic adhesive is preferably a copolymer of an alkyl (meth)acrylate having a C 1 to 10 alkyl group and a functional group-containing unsaturated monomer. An alkyl (meth) acrylate having an alkyl group having a carbon number of 匕 10 such as 2-ethylhexyl acrylate, butyl phthalate, isooctyl acrylate, butyl methacrylate or methyl 32 200829961 _Wait. Containing = energy base and monomers such as propyl benzoic acid, methacrylic acid, maleic acid, fumaric acid, propylene-based ethyl acetonate or hydroxyethyl methacrylate. Adhesive polymers such as a styrene-butadiene random copolymer, a stupid ethylene-isoprene fragment polymer or natural rubber, which are main components of the rubber-based adhesive, are preferred. The thickness of the adhesive layer is preferably 5 to ΙΟΟμπι. The surface material for the display is effective when it is placed on the outermost surface of the display body which may cause fingerprint contamination when touched by a hand. Specifically, for example, a personal computer, a word processor, a television, a mobile phone, a portable terminal, a game machine, an automatic cash register, a cash automatic payment machine, a vending machine, a navigation crack, or a security system terminal, etc. As a display panel for displaying images (CRT, plasma display, liquid crystal display, electric weeping display, field emission display, projection display, black and white display for electronic newspaper, etc.) The most surface. Further, it may be the outermost surface of the glass case or the plastic case of the display case or the display window used for the display display. For example, when used as a touch panel of a display, there is a separate type in which the above various displays are incorporated, or a separate type disposed on the display surface of each display device. As the method of the touch panel, any one of known methods can be used without any limitation. Specifically, it may be an ultrasonic method, a resistive film method, a capacitance method, an electric strain method, a magnetic strain method, an infrared method, or an electromagnetic induction method. From the viewpoint of power consumption and price, a resistive film type touch panel is preferable, and an electromagnetic induction type touch panel is preferable from the viewpoint of decomposition ability. Next, the action of the present embodiment will be described. The surface material for a display is formed by a transparent substrate and an antiglare layer (4) having a concave surface formed by a resin 33. When the surface material is placed on the surface of the electric touch panel, the surface of the surface material is pressed with a finger to perform the operation of the touch panel. At this time, since the surface of the surface material is attached with the fat component f from the body which forms a fingerprint mark, the visibility of the image f of the touch panel is lowered. Moreover, when the touch panel is in the electromagnetic induction mode, it is operated by the input pen operation (4) with a finger touch, but when the wheel is used to operate the pen, the palm touches the surface of the display, resulting in the lust from the body. The attachment of the component 'even if it is not handled, the fingertip is in contact with the display surface' may also adhere to the lipid component from the body. At this time, the visibility of the image of the touch panel is reduced as well as the resistance film. At this time, since the unevenness of the surface of the antiglare layer of the surface material is from 120 to 300, especially the Sm is 30 to 100 qing, the flicker is lowered. Also, by the surface: see =, the trace of the lipid from the body becomes = = the affinity of the layer for the lipid component from the body The lipid component of the body is quickly guided into the surface of the concave haze. Further, since the surface material is adjusted to the degree of blurring by the anti-glare sound f 50 / ° ', the degree of blurring can be adjusted, and the T-grain trace is difficult to become conspicuous. Therefore, the image of the touch panel is recognized by both: The following advantages can be obtained by the right π yoke. The high book quality of this embodiment shows that the surface of the anti-glare layer is flat and flat: the surface material of the anti-glare layer is used, and the anti-glare property is effectively achieved by hunting. The burial is from 1 to 1 and from 20 to 300 哗, up to 70 mN/m. (4) The surface energy of the glare layer becomes an affinity mark of 30 components?: The lipid hunted from the body is formed by the haze of the surface material. The value of 34 200829961 is 3 to 50%, making the fingerprint traces more difficult to stand out. As a result, the surface material has both an anti-glare function and a function that makes the fingerprint trace attached to the surface difficult to conspicuous, and the visibility of the display can be improved. • The average particle diameter of the fine particles forming the antiglare layer is set to a 'small range' and the content of the fine particles is set to a small amount. ^This, can be achieved, without the formation of excessive unevenness on the surface, to achieve anti-glare function, and can effectively achieve the effect of suppressing flicker and preventing illuminating. • By making the above functional layer a light scattering layer, it is possible to suppress flicker and improve the anti-glare function. • In the South Mussel display and the enamel touch panel, since the surface material for the above-mentioned enamel display is disposed on the surface, even for the display with high resolution and the touch panel, there is no flicker, and the fingerprint trace is difficult. Conspicuous. Hereinafter, the above embodiments will be more specifically described by way of examples and comparative examples. The indistinguishability of the fingerprint marks, the haze and the flicker of the fingerprints in each case were measured according to the methods shown below. (1) Difficulty difficulty of fingerprint marks • The following four levels of functional evaluation were performed by visually observing the difficulty of fingerprint marks attached to the surface material for a display. 4. Fingerprint traces are completely invisible. 3: Fingerprint traces are only faintly visible. 2: (10) Although it is still clear, it can be clearly seen. 1: Fingerprint traces are clearly visible. (2) Surface roughness using the Xiaoyan Institute Yinfen has a surface roughness measurement by P艮 company - machine Surfc〇der SE_0, under the condition of scanning range 1.5mm, scanning speed O.lmm/s 'according to JIS b 〇 6〇1-1994 specifies the arithmetic mean roughness Ra(pm), the ten-point average roughness Rz(4)), and the bump level 35 200829961. The interval is Sm(pm). (3) 60-degree gloss value According to JIS K7105, a 60-degree gloss value (%) was measured using a portable gloss meter HG-268 manufactured by Suga Test Machine Co., Ltd. (4) Surface energy The measurement was carried out in accordance with the method of JIS K6768 "Tensile test method". (5) Haze value The haze value (%) of the optical characteristic was measured using a direct reading haze value meter (manufactured by Toyo Seiki Seisakusho Co., Ltd., trade name: direct reading haze value meter (No. 206)). (6) Evaluation of the visibility of the display image The surface material of the display was mounted on the display, and the visibility of the image of the display was visually evaluated by visual observation according to the following four levels. 4: Bright, 3: slightly sharp, 2: slightly lacking in vividness, 1: image recognition is difficult. (7) Flickering prevention performance The surface material for the monitor is mounted on the surface of a high-quality display or a high-quality touch panel. By visually observing the flicker, the scintillation prevention performance is evaluated in the following three levels. 3: no flicker, 2: there are some flicker, 1: flicker. (Production Example 1) (Production of polyhexyl methacrylate) 75 g of mercaptoisobutyl ketone was placed in a 300 ml three-necked flask equipped with a stirrer, and the temperature was raised to 70 ° C under a nitrogen purge. Then, after reaching 70 ° C, 25 g of cyclohexyl methacrylate and 0.81 g of a polymerization initiator, tert-butyl peroxypivalate (Perbutyl PV) (Sakamoto Oil Co., Ltd. 36 200829961, 71%) The Shellsol dilutions were each divided into 3 portions and dropped in over 1 hour.
