Hereinafter, each step will be described.

(Release layer forming process)
The release layer forming step is a step of forming the release layer 3 on one surface of the base material 2 to be peeled off.

The base material 2 to be peeled off is not particularly limited. As an example, the base material 2 to be peeled off is a resin sheet, paper, cloth, rubber sheet, foam sheet or the like. The resin sheet is a polyolefin-based resin sheet such as polyethylene (PE), polypropylene (PP), ethylene / propylene copolymer; polyester-based such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polyethylene naphthalate (PEN). Examples thereof include a resin sheet; a vinyl chloride resin sheet; a vinyl acetate resin sheet; a polyethylene resin sheet; a polyamide resin sheet; a fluororesin sheet; and a cellophane. Examples of paper include Japanese paper, kraft paper, glassin paper, high-quality paper, synthetic paper, and top-coated paper. Examples of the cloth include woven cloths and non-woven fabrics made by spinning various fibrous substances alone or by blending them. Examples of the rubber sheet include a natural rubber sheet and a butyl rubber sheet. Examples of the foam sheet include a foamed polyolefin sheet such as a foamed PE sheet, a foamed polyester sheet, a foamed polyurethane sheet, and a foamed polychloroprene rubber sheet. Among these, the base material is preferably made of polyethylene terephthalate (PET) for reasons such as physical properties (for example, dimensional stability, thickness accuracy, workability, tensile strength), economy (cost), and the like. ..

The thickness of the base material 2 to be peeled off is not particularly limited. As an example, the thickness of the base material 2 to be peeled off is about 4 μm to 200 μm. When the thickness of the base material 2 to be peeled is within the above range, the base material is less likely to be curled or wrinkled, has excellent transferability, and can be kept at low cost.

The release layer 3 is not particularly limited. For example, the release layer 3 is made of a release agent such as a silicone resin type, a fluororesin type, a cellulose derivative resin type, a urea resin type, a polyolefin resin type, and a melamine resin type.

The method for forming the release layer 3 is not particularly limited. As an example, the release layer 3 can be formed by applying a release agent on the base material 2 to be peeled off using a roll coater or the like.

The thickness of the release layer 3 is not particularly limited. As an example, the thickness of the release layer 3 is about 0.01 to 5 μm.

(Protective layer forming process)
The protective layer forming step is a step of forming a protective layer 4 containing an ultraviolet curable resin composition on the release layer 3.

The protective layer 4 is not particularly limited. As an example, the protective layer 4 may contain an ultraviolet curable resin composition. As an example, the ultraviolet curable resin composition is an ultraviolet radical curing composed of an ultraviolet curable monomer such as an epoxy acrylate resin, a urethane acrylate resin, a heat curable acrylic resin, or a prepolymer thereof, and a photoradical polymerization initiator. A mold resin composition, an ultraviolet curable epoxy resin as a resin component, a cationic ultraviolet polymerization initiator as a photopolymerization initiator, and if necessary, a cationically polymerizable vinyl monomer, a diluent, other epoxy resins, and sensitization. It is a cation-curable resin composition containing an agent, a cross-linking agent, and the like.

The thickness of the protective layer 4 is not particularly limited. As an example, the thickness of the protective layer 4 is preferably 1.0 μm or more and 20 μm or less. When the thickness of the protective layer 4 is within the above range, the decorative film molded body 1 is excellent in scratch resistance and abrasion resistance.

The method of forming the protective layer 4 is not particularly limited. As an example, the protective layer 4 can be formed by applying a resin solution constituting the protective layer 4 appropriately dissolved in a solvent onto the release layer 3 using a roll coater or the like. The applied resin solution is cured in the temporary curing step and the main curing step described later.

(Thin-film deposition layer forming process)
The thin-film deposition layer forming step is a step of forming the thin-film deposition layer 5 on the protective layer 4.

The vapor deposition layer 5 is not particularly limited. As an example, the vapor-deposited layer 5 is at least one type (also referred to as a metal or the like) selected from the group consisting of non-metals, metals, metal oxides and metal nitrides. Non-metals, metals and the like are not particularly limited. As an example, the non-metal is amorphous carbon (DLC) and its composite, the metal and the like are at least one metal selected from the group consisting of silicon, titanium, tin, zinc, aluminum, indium and magnesium, and its oxidation. A thing, its nitride. Among these, the metal and the like are preferably aluminum, aluminum oxide, indium, tin, silicon oxide, silicon nitride, silicon nitride, aluminum zinc oxide (AZO), zinc tin oxide (ZTO) and the like, and aluminum. , Aluminum oxide, indium and tin are more preferred. Since the vapor-deposited layer 5 is made of aluminum, aluminum oxide, indium, and tin, the obtained decorative film molded body 1 tends to exhibit a metallic design feeling of satin plating.

The method for forming the vapor deposition layer 5 is not particularly limited. As an example, as the vapor deposition method, a conventionally known vacuum vapor deposition method, a sputtering method, a physical vapor deposition method such as an ion plating method, a chemical vapor deposition method, or the like can be appropriately adopted. Among these, in the method for producing the decorative film molded body 1 of the present embodiment, it is preferable to provide the vapor deposition layer 5 by the vacuum vapor deposition method because of its high productivity. As the vapor deposition conditions, conventionally known conditions can be appropriately adopted based on the material of the vapor deposition layer 5 and the desired thickness of the vapor deposition layer. When depositing a metal, the metal material preferably has few impurities and a purity of 99% by weight or more, and more preferably 99.5% by weight or more. Further, the metal material is preferably processed into a granular shape, a rod shape, a tablet shape, a wire shape, or a crucible shape to be used. The heating method for evaporating the metal material is a method of putting the metal material in the crucible and performing resistance heating or high frequency heating, a method of performing electron beam heating, or putting the metal material directly on a ceramic board such as boron nitride. A well-known method such as a method of performing resistance heating can be used. The crucible used for vacuum deposition is preferably made of carbon, and may be alumina, magnesia, titania, or beryllium crucible.

The thickness of the vapor deposition layer 5 is not particularly limited. As an example, the thickness of the vapor deposition layer 5 is preferably 7 nm or more, and more preferably 20 nm or more. The thickness of the thin-film deposition layer 5 is preferably 100 nm or less, more preferably 80 nm or less. When the thickness of the thin-film deposition layer 5 is within the above range, the thin-film deposition layer 5 has appropriate flexibility, and unevenness 51 (see FIG. 2) is likely to be formed on the surface by the filler F described later.

(Adhesive layer forming process)
The adhesive layer forming step is a step of forming the adhesive layer 6 containing the filler F on the vapor deposition layer 5.

The resin constituting the adhesive layer 6 is not particularly limited. For example, the adhesive layer 6 is made of acrylic resin, urethane resin, urethane-modified polyester resin, polyester resin, epoxy resin, ethylene-vinyl acetate copolymer resin (EVA), vinyl resin (PVC, vinyl chloride, etc.). Vinegar, vinyl chloride-vinegar copolymer resin), styrene-ethylene-butylene copolymer resin, polyvinyl alcohol resin, polyacrylamide resin, polyacrylamide resin, isobutylene rubber, isoprene rubber, natural rubber, SBR, NBR , Made of resin such as silicone rubber. These resins may be appropriately dissolved in a solvent and used, or may be used without a solvent.

The thickness of the adhesive layer 6 is not particularly limited. As an example, the thickness of the adhesive layer 6 is about 0.5 to 5 μm.

The filler F is added to form the unevenness 51 on the surface of the vapor deposition layer 5 in the transfer base material forming step described later.

The filler F is not particularly limited. As an example, the filler F is melamine-based resin particles, acrylic-based resin particles, acrylic-styrene-based copolymer particles, polycarbonate-based particles, polyethylene-based particles, and polystyrene-based particles. Further, the filler F may be silica particles, talc, boron nitride or the like.

The shape of the filler F is not particularly limited. The shape of the filler F may be various fixed shapes, or may be an irregular shape such as a lens shape or a scale shape. FIG. 1 illustrates a lens-shaped filler F (lens-shaped filler F).

The shape of the amorphous filler is preferably a shape other than a true sphere, and more preferably a lenticular shape (elliptical sphere) or a scaly shape. Since the shape of the amorphous filler is other than a spherical shape, the filler does not diffuse light in all directions and does not easily exhibit a whitish appearance. As a result, the obtained decorative film molded body 1 can easily express the metallic tone of satin plating.

The dimensions of the amorphous filler are not particularly limited. As an example, when the amorphous filler is a lenticular filler, the major axis L1 of the lenticular filler F is preferably 2.0 μm or more, and more preferably 6.0 μm or more. The major axis L1 of the lens-shaped filler F is preferably 20 μm or less, and more preferably 10 μm or less. The thickness L2 of the lens-shaped filler F is preferably 1.0 μm or more, and more preferably 2.0 μm or more. The thickness L2 of the lens-shaped filler F is preferably 5.0 μm or less, and more preferably 3.0 μm or less. Further, the aspect ratio (major axis / thickness) of the lenticular filler F is preferably 1.0 or more, and more preferably 2.0 or more. The aspect ratio of the lenticular filler F is preferably 10 or less, more preferably 5.0 or less. When the size of the lenticular filler F is within the above range, unevenness 51 having a desired size is likely to be formed on the surface of the vapor deposition layer 5 in the transfer base material forming step described later. As a result, the obtained decorative film molded body 1 tends to have both metallic luster and low image quality.

On the other hand, when the amorphous filler is a scaly filler, the major axis of the scaly filler is preferably 0.5 μm or more and 10 μm or less. The thickness of the scaly filler is preferably 0.05 μm or more and 0.5 μm or less. Further, the aspect ratio (major axis / thickness) of the scaly filler is preferably 10 or more and 150 or less. When the size of the scaly filler is within the above range, unevenness of a desired size is likely to be formed on the surface of the vapor-deposited layer in the transfer base material forming step described later. As a result, the obtained decorative film molded product tends to have both metallic luster and low image quality.

When the adhesive layer 6 containing the filler is formed on the thin-film deposition layer 5, the adhesive layer 6 solidifies in a state where a part of the filler F is exposed from the surface of the adhesive layer 6. FIG. 1 shows a state in which a part of the lenticular filler F is solidified in a state of being exposed from the surface of the adhesive layer 6.

The method for forming the adhesive layer 6 is not particularly limited. As an example, the adhesive layer 6 can be formed by applying a resin solution constituting the adhesive layer 6 appropriately dissolved in a solvent onto the vapor-deposited layer 5 using a roll coater or the like.

(Shielding process)
FIG. 4 is a schematic diagram for explaining the shielding process. The shielding step is a step of arranging a shielding plate 8 including a shielding portion 81 that shields ultraviolet rays and a non-shielding portion 82 that transmits ultraviolet rays on the other surface of the base material 2 to be peeled off. The shielding step may be performed before the transfer substrate forming step.

The shielding plate 8 is formed with a shielding portion 81 that shields ultraviolet rays and a non-shielding portion 82 that transmits ultraviolet rays. The material of the shielding plate 8 is not particularly limited. As an example, the shielding plate 8 is made of various resin materials, glass, or the like.

The surface of the shielding portion 81 is black and has a low transmittance for ultraviolet rays. As a result, the ultraviolet rays radiated to the shielding plate 8 do not pass through the shielding portion 81, but mainly pass through the non-shielding portion 82. The ultraviolet rays transmitted through the non-shielding portion 82 reach the protective layer 4, and in the temporary curing step described later, a part of the protective layer 4 is cured (temporarily cured) along the shape of the non-shielding portion 82.

The shape of the non-shielding portion 82 is not particularly limited. As an example, the shape of the non-shielding portion 82 can be appropriately determined according to a desired pattern. FIG. 4 illustrates a case where the shape of the non-shielding portion 82 is a plurality of rhombuses. The shielding portion 81 does not have to completely shield ultraviolet rays. At least, the non-shielding portion 82 and the shielding portion 81 may have a predetermined difference in transmittance with respect to ultraviolet rays.

(Temporary curing process)
The temporary curing step is a step of irradiating ultraviolet rays from the protective layer 4 toward the adhesive layer 6 so as to pass through the non-shielding portion 82 to temporarily cure the protective layer 4. The temporary curing step may be carried out after the above-mentioned shielding step and before the transfer base material forming step described later.

The method of irradiating ultraviolet rays is not particularly limited. As an example, ultraviolet rays are emitted from the protective layer 4 to an adhesive layer using an ultraviolet irradiation device (ECS-4011GX (using a high-pressure mercury lamp), manufactured by Eye Graphics Co., Ltd.) so that the integrated light amount is 500 mJ / cm ^2. It can irradiate in 6 directions. The irradiated ultraviolet rays do not pass through the shielding portion 81 of the shielding plate 8, but mainly pass through the non-shielding portion 82. The ultraviolet rays transmitted through the non-shielding portion 82 reach the protective layer 4, and a part of the protective layer 4 is cured (temporarily cured) along the shape of the non-shielding portion 82 (a plurality of rhombuses in the present embodiment).

(Transfer substrate forming step)
The transfer base material forming step is a step of forming (mounting) the transfer base material 7 on the adhesive layer 6.

The transfer base material 7 (base material) is not particularly limited. The base material is a resin sheet, paper, cloth, rubber sheet, foam sheet, glass or the like. The resin sheet is a polyolefin resin sheet such as acrylonitrile-styrene (AS), acrylonitrile-butadiene-styrene (ABS), various acrylates, polycarbonate (PC), polyethylene (PE), polypropylene (PP), ethylene / propylene copolymer, etc. Polyethylene resin sheet such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyethylene naphthalate (PEN); vinyl chloride resin sheet; vinyl acetate resin sheet; polyimide resin sheet; polyamide resin sheet; fluororesin sheet; cellophane Etc. are exemplified. Examples of paper include Japanese paper, kraft paper, glassin paper, high-quality paper, synthetic paper, and top-coated paper. Examples of the cloth include woven cloths and non-woven fabrics made by spinning various fibrous substances alone or by blending them. Examples of the rubber sheet include a natural rubber sheet and a butyl rubber sheet. Examples of the foam sheet include a foamed polyolefin sheet such as a foamed PE sheet, a foamed polyester sheet, a foamed polyurethane sheet, and a foamed polychloroprene rubber sheet. Among these, the base material is preferably made of acrylonitrile-styrene (AS) or acrylonitrile-butadiene-styrene (ABS) because of its excellent surface resistance and processability.

The thickness of the base material is not particularly limited. As an example, the thickness of the base material is about 4 μm to 10 mm. When the thickness of the base material is within the above range, the base material has excellent processability and is easily transferred without impairing the appearance.

As shown in FIG. 1, when the transfer base material 7 is pressed against the adhesive layer 6 on which the lenticular filler F is exposed, the exposed lenticular filler F is pushed in the thickness direction of the adhesive layer 6. Is done. As a result, as shown in FIG. 2, the lenticular filler F is buried in the thickness direction of the adhesive layer 6 and deforms the vapor deposition layer 5. As a result, unevenness 51 (a substantially bowl-shaped convex portion protruding toward the protective layer 4 side) is formed on the surface of the vapor-deposited layer 5. As described above, the thickness of the lenticular filler F is preferably larger than the thickness of the adhesive layer 6. As a result, unevenness 51 is likely to be formed on the surface of the vapor deposition layer 5.

The maximum diameter of the convex portion is preferably 2.0 μm or more and 20 μm or less. The height of the convex portion is preferably 0.5 μm or more and 5.0 μm or less. When the maximum diameter and height of the convex portion are within the above ranges, the degree of matting of the obtained decorative film molded body 1 can be easily adjusted appropriately. As a result, in the decorative film molded body 1, the appropriate mattness and the gloss property that contributes to the contrast are easily adjusted appropriately, and the metallic design feeling of satin plating can be reproduced more accurately.

(Peeling process)
The peeling step is a step of peeling the base material 2 to be peeled and the release layer 3. As shown in FIGS. 2 and 3, according to the peeling step, the base material 2 to be peeled off and the release layer 3 are peeled off. As a result, the protective layer 4 is exposed.

(Main curing process)
The main curing step is a step of irradiating ultraviolet rays from the protective layer 4 toward the adhesive layer 6 to main cure the protective layer 4. This curing step may be performed after the transfer substrate forming step. The shielding plate 8 arranged in the shielding step may be removed in a timely manner before the main curing step is performed. The main curing step is preferably carried out after the peeling step. As a result, in this curing step, the protective layer exposed by the peeling step is irradiated with ultraviolet rays. Therefore, the obtained decorative film molded product is likely to be cured more uniformly.

The method of irradiating ultraviolet rays is not particularly limited. As an example, ultraviolet rays are emitted from the protective layer 4 to an adhesive layer using an ultraviolet irradiation device (ECS-4011GX (using a high-pressure mercury lamp), manufactured by Eye Graphics Co., Ltd.) so that the integrated light intensity is 1000 mJ / cm ^2. It can irradiate in 6 directions. The irradiated ultraviolet rays reach the protective layer 4 and cure (mainly cure) the entire protective layer 4 including the portion (a plurality of rhombuses in the present embodiment) that has been temporarily cured in the above-mentioned temporary curing step.

As described above, according to the present embodiment, the protective layer 4 is cured along the shape of the non-shielding portion 82 by the ultraviolet rays transmitted through the non-shielding portion 82 in the temporary curing step. After that, in the transfer substrate forming step, the filler F is embedded in the adhesive layer 6 and the vapor deposition layer 5 is deformed to form the unevenness 51. Further, in the main curing step, the entire protective layer 4 is cured. As a result, the first cured portion of the protective layer 4 and the surrounding portion are cured by separate steps (temporary curing step and main curing step), and the pattern having a faint outline is protected. It is formed in layer 4. Further, when viewed from the direction from the protective layer 4 to the adhesive layer 6, the unevenness 51 formed on the vapor-deposited layer 5 is formed at a position that does not overlap with the pattern with the unevenness 51 formed at a position that overlaps with the pattern in the top view. There is an uneven film 51. All of these unevenness 51 do not affect the outline of the design when the light is reflected so as to make the outline of the design stand out (when the design is visible) when the unevenness 51 is tilted by a predetermined angle. It can change to the case of reflecting light (a state in which the design is difficult to see).

FIG. 5 is a schematic view showing a state in which the decorative film molded body 1 is tilted so that the design is difficult to see. FIG. 6 is a schematic view showing a state in which the decorative film molded body 1 is tilted so that the design can be visually recognized. FIG. 7 is a photograph showing a state in which the decorative film molded body 1 is tilted so that the design is difficult to see. FIG. 8 is a photograph showing a state in which the decorative film molded body 1 is tilted so that the design can be visually recognized.

Further, the decorative film molded body 1a of the present embodiment is suitable for the various uses described above in the first embodiment.

<Third embodiment>
The method for producing a decorative film molded product according to an embodiment of the present invention includes a release layer forming step of forming a release layer on one surface of a substrate to be peeled off, and an ultraviolet curable type on the release layer. A protective layer forming step of forming a protective layer containing a resin composition, a vapor deposition layer step of forming a vapor deposition layer on the protective layer, a printing step of forming a printing portion on the vapor deposition layer, and formation of a printing portion. By forming an adhesive layer containing a filler on the vapor-deposited layer and pressing a transfer base material on the adhesive layer, the filler is embedded in the adhesive layer to make the surface of the vapor-deposited layer uneven. It includes a transfer base material forming step of forming a transfer base material by pressing the printed layer against the vapor deposition layer to deform the vapor deposition base material, and a peeling step of peeling off the peeled base material and the release layer. Hereinafter, each step will be described. In the following description, the description of the same steps as those in the first embodiment or the second embodiment described above will be omitted as appropriate.

(Release layer forming process, protective layer forming process, thin-film deposition layer forming process and printing process)
The release layer forming step is a step of forming a release layer on one surface of the base material to be peeled off. The protective layer forming step is a step of forming a protective layer containing an ultraviolet curable resin composition on the release layer. The thin-film deposition layer forming step is a step of forming a thin-film deposition layer on the protective layer. The printing step is a step of forming a printed portion on the vapor-deposited layer. The release layer forming step, the protective layer forming step, the vapor deposition layer forming step, and the printing step are all as described above in the second embodiment.

(Adhesive layer forming process)
The adhesive layer forming step is a step of forming an adhesive layer containing a filler on the vapor-deposited layer on which the printed portion is formed. The adhesive layer forming step of the present embodiment is the same as the adhesive layer forming step of the second embodiment described above, except that the filler is included. The filler is similar to that described above in the first embodiment.

According to the adhesive layer forming step, the adhesive layer is formed so as to cover the vapor-deposited layer on which the printed portion is formed. When the adhesive layer containing the filler is formed on the vapor-deposited layer, the adhesive layer solidifies with a part of the filler exposed from the surface of the adhesive layer.

(Transfer substrate forming step)
In the transfer base material forming step, the transfer base material is pressed onto the adhesive layer to embed the filler in the adhesive layer to form irregularities on the surface of the vapor deposition layer, and the printing layer is pressed against the vapor deposition layer. This is a step of deforming the thin-film deposition layer to form (mount) a transfer base material. The type and size of the transfer base material are the same as those described above in the first embodiment.

When the transfer base material is pressed onto the adhesive layer, the printed portion provided on the vapor-deposited layer is pushed in the thickness direction of the vapor-deposited layer via the adhesive layer. As a result, the printing unit deforms the vapor-deposited layer. As a result, unevenness (convex portion protruding toward the protective layer side) is formed on the surface of the thin-film deposition layer along the shape of the printed portion (that is, the shape of the pattern).

Further, when the transfer base material is pressed onto the adhesive layer, the exposed filler is pushed in the thickness direction of the adhesive layer. As a result, the filler is buried in the thickness direction of the adhesive layer and deforms the vapor-deposited layer. As a result, unevenness (second unevenness) having a dimension different from the unevenness formed by the above-mentioned printing portion is formed on the surface of the thin-film deposition layer. As described above, the thickness of the filler is preferably larger than the thickness of the adhesive layer. As a result, unevenness is likely to be formed on the surface of the thin-film deposition layer.

(Curing process)
The curing step is a step of irradiating ultraviolet rays from the protective layer toward the adhesive layer to cure the protective layer. The curing step is the same as the main curing step described above.

(Peeling process)
The peeling step is a step of peeling the base material to be peeled and the release layer. According to the peeling step, the base material to be peeled off and the release layer are peeled off. As a result, the protective layer is exposed.

As described above, according to the present embodiment, the vapor-deposited layer is deformed along the shape of the pattern (printing portion) inside the decorative film molded body. Further, a design is provided as a printing portion inside the decorative film molded body. Further, the thin-film deposition layer has fine irregularities formed by the filler. When viewed from the direction from the protective layer to the adhesive layer, the fine irregularities formed on the vapor-deposited layer are formed at positions that overlap with the pattern that is the printed portion in the top view and at positions that do not overlap with the pattern. There are fine irregularities. As a result, the degree of light reflection varies between the printed portion and its surroundings. Specifically, the decorative film molded product of the present embodiment reflects light so as to make the outline of the design stand out when tilted by a predetermined angle (the state in which the design is visible), and the outline of the design. It can change to the case where light is reflected so as not to affect (the pattern is difficult to see).

In the decorative film molded product of the present embodiment, the printing portion constituting the pattern is provided inside the decorative film molded product in this way, and it is extremely difficult to duplicate the decorative film molded product. Moreover, the surface of the protective layer is flat. Therefore, even if the surface of the protective layer is touched, the shape of the design cannot be confirmed. As a result, the decorative film molded product obtained in the present embodiment has, for example, a technique for imparting a function for preventing counterfeiting to a medium such as banknotes and securities, and an anti-counterfeiting property for a product package. It is suitable as a technique for imparting decoration. In addition, the decorative film molded product of the present embodiment is suitable for the various uses described above in the first embodiment.

In the above embodiment, the case where the surface of the protective layer is flat has been described. However, the present invention is not limited to this. The decorative film molded product of the present invention may be provided with irregularities on the surface of the protective layer as appropriate. As a result, the decorative film molded body has a unique dull metallic luster like satin plating, and is given a matte-like design, so that reflection of a human face, external light, illumination light, etc. can be reduced. ..

<Decorative film molded body>
The decorative film molded product according to the embodiment of the present invention has a base material, an adhesive layer, a vapor-deposited layer, and a protective layer. The vapor-film layer has irregularities formed on its surface. The adhesive layer contains a filler. The protective layer has a first region and a second region having a higher degree of polymerization than the first region. When light from the light source of the multi-angle colorimeter is incident from an angle 45 ° inclined from the normal direction of the protective layer, the normal reflection direction of the incident light is defined as 0 °, and the light source is defined as the normal reflection direction. When the side is defined as a positive angle and the side opposite to the light source is defined as a negative angle from the normal reflection direction, the L * value (L1 * _-15 ) in the -15 ° direction in the first region is the second region. The L * value in the 15 ° direction (L1 * ₁₅ ) in the first region is larger than the L * value (L2 * _-15 ) in the -15 ° direction in the first region, and the L * value (L2) in the 15 ° direction in the second region. It _{is larger than * 15 ), and the L * value (L1 * 25} ) in the 25 ° direction in the first region is larger than _{the L * value (L2 * 25} ) in the 25 ° direction in the second region. Each will be described below. In the following description, the description of the same structure as the above-mentioned structure (for example, base material, adhesive layer, thin-film deposition layer, protective layer, filler, etc.) related to the method for manufacturing the decorative film molded body will be omitted as appropriate. Will be done.

In the decorative film of the present embodiment, the protective layer has a first region and a second region. Both the first region and the second region are layers in which the resin solution constituting the protective layer is cured. The second region of the present embodiment has a higher degree of polymerization than the first region. That is, in the second region, the resin solution constituting the second region is more cured than the resin solution constituting the first region.

The method of increasing the degree of polymerization of the second region as compared with that of the first region is not particularly limited. As an example, in the second region, as described in connection with FIG. 4, the protective layer 4 is temporarily cured by covering the base material 2 to be peeled with the shielding plate 8 and allowing ultraviolet rays to pass through the non-shielding portion 82. Then, by removing the shielding plate 8 and mainly curing the entire protective layer 4, the degree of polymerization can be adjusted to be large. According to such a method, in the protective layer, the region where the temporary curing and the main curing are performed (second region) is more cured than the region where only the main curing is performed (the first region). It is more advanced and the degree of polymerization is higher.

The decorative film molded product of the present embodiment is particularly preferably produced by the above-mentioned production method in relation to the production method of the decorative film molded product. That is, in the temporary curing step, a part of the protective layer is cured. Next, in the transfer base material forming step, the filler contained in the adhesive layer is pressed against the adhesive layer by the transfer base material to form irregularities on the surface of the vapor deposition layer. Then, in the main curing step, the entire protective layer is finally cured. As a result, the first cured portion of the protective layer and the surrounding portion are cured by separate steps (temporary curing step and main curing step), and the pattern having a faint outline is formed in the protective layer. Is formed in. Further, when viewed from the direction from the protective layer to the adhesive layer, the unevenness formed on the vapor-deposited layer includes unevenness formed at a position overlapping the symbol in the top view and unevenness formed at a position not overlapping the symbol. .. All of these irregularities reflect light so as to make the outline of the design stand out when tilted by a predetermined angle (when the design is visible), and light so as not to affect the outline of the design. Can change to the case of reflecting (a state in which the design is difficult to see).

More specifically, in the decorative film molded product of the present embodiment, the first region and the second region having different degrees of polymerization described above can be measured by using a multi-angle colorimeter in the highlight region L *. The values are characterized in that they indicate a predetermined relationship. FIG. 12 is a schematic view for explaining a state in which light from a light source of a multi-angle colorimeter is incident on the decorative film molded product of the present embodiment. ND indicates the normal direction. In the present embodiment, the multi-angle colorimeter may use "MA-T6" manufactured by x-rite, and a pleochroic white LED (D65 light source) may be used as the light source. The measurement area may be 20 mm × 30 mm.

As shown in FIG. 12, when light from the light source L of the multi-angle colorimeter is incident on each of the first region and the second region of the protective layer 4 from an angle θ1 inclined by 45 °, it is positive. The reflection direction RD is defined as 0 °. Further, the light source L side from the specular reflection direction RD is defined as a positive angle, and the side opposite to the light source from the specular reflection direction is defined as a negative angle. Then, L * in the -15 ° direction R _-15 , the 15 ° direction R ₁₅ , the 25 ° direction R ₂₅ , the 45 ° direction R ₄₅ , the 75 ° direction R ₇₅ , and the 110 ° direction R _{110 is measured.}

In the decorative film molded product of the present embodiment, the L * value (L1 * _-15 ) in the -15 ° direction in the first region is higher than _{the L * value (L2 * -15) in the -15 ° direction in the second region.} Is also big. Similarly, the L * value (L1 * ₁₅ ) in the 15 ° direction in the first region is larger than _{the L * value (L2 * 15) in the 15 ° direction in the second region.} Further, the L * value (L1 * ₂₅ ) in the 25 ° direction in the first region is larger than _{the L * value (L2 * 25) in the 25 ° direction in the second region.} As described above, in the decorative film molded product of the present embodiment, the L * value of the first region is the highest in the highlight regions such as −15 °, 15 °, and 25 °, which are in the vicinity of the specular reflection direction RD. It is larger than the L * value of the two regions. Therefore, when the decorative film molded product is tilted by a predetermined angle, the design can be visually recognized depending on the difference in the degree of reflection based on the difference in the L * value between the first region and the second region. It is possible to switch to a state where it is difficult to see. In addition, various base materials can be used for the decorative film molded product.

Further, in the decorative film molded product of the present embodiment, the difference in L * value between the first region and the second region is small in the region other than the highlight region (for example, the shade region). Specifically, the decorative film molded product of the present embodiment has an L * value (L1 * ₇₅ ) in the 75 ° direction in the first region and an L * value (L2 * ₇₅ ) in the 75 ° direction in the second region. Is about the same. Similarly, the L * value (L1 * ₁₁₀ ) in the 110 ° direction in the first region is about the same as _{the L * value (L2 * 110) in the 110 ° direction in the second region.}

As described above, when the decorative film molded product of the present embodiment is visually recognized from the angle of the highlight region, the difference in L * value becomes remarkable and the design is easily visible, but when visually recognized from the angle of the shade region, There is almost no difference in L * values, making it difficult to see the design.

Hereinafter, the present invention will be described in more detail with reference to Examples. The present invention is not limited to these examples. Unless otherwise specified, "%" means "mass%" and "part" means "parts by mass".

Then, using an ultraviolet irradiation device (ECS-4011GX (using a high-pressure mercury lamp), manufactured by Eye Graphics Co., Ltd.), irradiation was performed from the protective layer to the adhesive layer so ^{that the integrated light intensity was 1000 mJ / cm 2 (this).} Curing process). In Example 3, for the purpose of more clearly understanding the effect of the present invention and for the reason that the measurement by the multi-angle colorimeter can only be measured with a relatively large sample, protection is performed without performing a shielding step. The entire surface of the layer was temporarily cured and finally cured. As a result, in Example 3, the second region was reproduced. On the other hand, in Example 4 described later, the temporary curing step was not carried out. As a result, the first region was reproduced.

(Example 4)
A polyethylene terephthalate (PET) film (thickness: 25 μm) was used as a base material to be peeled off, and an acrylic styrene resin (addition amount: 91 parts) and a curing agent (isocyanate, addition: 9 parts) were coated with a bar coater. This uncured resin layer was cured at 50 ° C. for 48 hours to prepare a release layer (thickness: 1.0 μm) (release layer forming step). A polyfunctional acrylate resin solution (97 parts) and a photopolymerization curing agent (addition amount: 3 parts) were applied on the release layer with a bar coater to prepare a protective layer (thickness: 5.0 μm) (protection). Layer formation step). Acrylic resin (addition amount: 100 parts) was applied on the protective layer with a bar coater. This uncured resin layer was cured at 110 ° C. for 30 seconds to prepare a thin-film deposition anchor layer (thickness: 1.0 μm). Aluminum was vacuum-deposited on the vapor deposition anchor layer using a resistance heating type vapor deposition machine. An aluminum film (deposited layer) having a thickness of 35 nm was formed (deposited layer forming step). Acrylic resin (addition amount: 38 parts), urethane resin solution (addition amount: 57 parts), lenticular filler (acrylic, manufactured by Sekisui Kasei Kogyo Co., Ltd., dimensions: major axis 7.2 μm, thickness 2.8 μm, on the vapor deposition layer, The addition amount: 5 parts) was applied with a bar coater to prepare an adhesive layer (thickness: 1.0 μm) (adhesive layer forming step). After that, a black ABS plate (transfer base material) is placed on the adhesive layer using an up-down transfer machine (MP-6 manufactured by Navitas Co., Ltd.), a pressing load of 1 kN, a marking temperature of 180 ° C., and a transfer time of 1.0 s. The filler was embedded in the adhesive layer under the above conditions (transfer substrate forming step). As a result, the thin-film deposition layer was deformed and irregularities were formed on the surface of the vapor-deposited layer (details of irregularities: convex shape with an average major axis of 4.1 μm and a height of 0.3 to 0.5 μm). Then, the base material to be peeled and the release layer were peeled off (peeling step). Then, using an ultraviolet irradiation device (ECS-4011GX (using a high-pressure mercury lamp), manufactured by Eye Graphics Co., Ltd.), irradiation was performed from the protective layer to the adhesive layer so ^{that the integrated light intensity was 1000 mJ / cm 2 (this).} Curing process).

For the decorative film molded products obtained in Examples 1 to 4, the L * values at various angles were measured by the following methods. The results are shown in Table 1.

<Measurement of L * value>
When the light from the light source of the multi-angle colorimeter is incident from an angle 45 ° inclined from the normal direction of the protective layer of each decorative film molded body, the specular reflection direction of the incident light is defined as 0 °. Then, in the case where the light source side from the specular reflection direction is defined as a positive angle and the side opposite to the light source from the specular reflection direction is defined as a negative angle, the first region (Examples 2 and 4) and the second The L * values in the regions (Example 1 and Example 3) were measured. The angles at the time of measurement were -15 ° direction, 15 ° direction, 25 ° direction, 45 ° direction, 75 ° direction, and 110 ° direction. As the multi-angle colorimeter, "MA-T6" manufactured by x-rite was used, and a pleochroic white LED (D65 light source) was used as the light source. The measurement area was 20 mm × 30 mm.

As shown in Table 1, a comparison between Example 1 in which the entire surface was temporarily cured assuming the second region and Example 2 in which the first region was assumed and not temporarily cured is compared, and the highlight region (-15) The L * values in (° to 25 °) were larger in Example 2 than in Example 1. In addition, there was almost no difference in the L * value in the shade region between Example 1 and Example 2. As a result, the decorative film molded body including the second region of the first embodiment and the first region of the second embodiment becomes the first region and the second region when tilted by a predetermined angle. It was shown that the design can be switched between a visible state and a hard-to-see state by the difference in the degree of reflection based on the difference in the L * value. The same was true for Example 3 and Example 4.
