Definitions
- the present invention relates to an activator for a hydraulic transfer film, and more specifically, reproduces (recovers) the adhesion of a dry printed pattern on the hydraulic transfer film to be hydraulically transferred to the surface of an article to be decorated. Therefore, prior to the hydraulic transfer, the invention relates to an improvement in the activator for the hydraulic transfer film that is applied to the print pattern.
- a hydraulic transfer film having a water-insoluble printing pattern is floated on the water surface in the transfer tank, and this hydraulic transfer is performed. After the water-soluble film of the film is wetted with water, the article (transfer object) is pushed into the water in the transfer layer while being in contact with the printing pattern of the hydraulic transfer film.
- a water pressure transfer method is used in which a printing pattern of a water pressure transfer film is transferred to the surface of an article by using water pressure to form a decorative layer.
- the hydraulic transfer film is stored on a water-soluble film in which a print pattern is printed and dried and wound into a roll, the ink of the print pattern is in a dry state that loses adhesion.
- a solvent such as an activator or thinner to the printed pattern on the hydraulic transfer film so that the printed pattern is in a wet state just after printing (returns to an adhesive state).
- the treatment is usually referred to as an activation treatment.
- the decorative layer formed on the surface of the article by hydraulic transfer in this way is mechanically and chemically protected by abrasion, solvent resistance, chemical resistance, weather resistance, etc., and has high strength on the surface of the article. It is required that it does not adhere and peel.
- the present applicant has previously proposed an invention in which a decorative layer is hydraulically transferred while imparting abrasion resistance, solvent resistance, etc. to the decorative layer itself without applying a topcoat layer on the decorative layer ( (See Patent Documents 1 to 3).
- an ultraviolet curable resin composition containing a non-solvent-type activating component such as a photopolymerizable monomer that reproduces adhesion to a dry printed pattern of a hydraulic transfer film is applied, and this ultraviolet curable resin is applied.
- the printing pattern adhesion is reproduced by the activating component of the resin composition, and the printing pattern is hydraulically transferred onto the transfer object in a state where the ultraviolet curable resin composition penetrates the entire printing pattern.
- the decorative layer formed by the printed pattern is given a state of UV curability, and the decorative layer itself has chemical properties such as solvent resistance and abrasion resistance. And mechanical surface protection function.
- the UV curable resin composition is applied to the hydraulic transfer film to reproduce the adhesion of the dry printed pattern, and the UV curable resin composition is applied to the printed pattern to impart UV curable properties to the printed pattern.
- the UV curable resin composition is ideally evenly distributed over the entire printed pattern once dried and solidified. It requires a relatively low viscosity that allows penetration and an ink solubility that can restore adhesion by dissolving the ink, and this UV curable resin composition can be printed at the required coating amount during hydraulic transfer. It is desired to be applied to the pattern.
- the UV curable resin composition If the UV curable resin composition is too high in viscosity, the UV curable resin composition will not penetrate into the entire printed pattern in an appropriate amount, and if the UV curable resin composition has low ink solubility, it is in a dried and solidified state. The adhesion of the printed pattern cannot be reproduced, and if the applied amount of the ultraviolet curable resin composition is too small, the ultraviolet curable resin composition does not reach the surface of the printed pattern (the outer surface after transfer).
- the viscosity of the ultraviolet curable resin composition is too low or the coating amount is too large, the printed pattern will be destroyed, resulting in a phenomenon that the pattern is blurred.
- the UV curable resin composition has a predetermined viscosity and ink solubility. And the coating amount are required.
- the natural integration of the UV curable resin does not mean a state where it is partially mixed with the print pattern, but preferably a state where it is generally mixed evenly with the print pattern.
- the UV curable resin composition is mixed only on the resin composition application side of the printed pattern, but if the UV curable resin composition does not reach the outer surface after transfer, the decorative layer that is the outermost surface of the decorative layer The surface is not provided with a surface protection function such as solvent resistance.
- a commercially available UV curable resin composition contains at least a photopolymerizable prepolymer, a photopolymerizable monomer, and a photoinitiator, but after penetrating the entire dry ink of the hydraulic transfer film and receiving UV irradiation. Since it was not integrated with the ink, it was not intended to be cured with the ink, as if the ink was given UV-curing properties. Although it could be applied to low- or middle-grade hydraulic transfer, it was sufficiently satisfactory for high-end or ultra-high-end hydraulic transfer that required a fine design like Motoki when decorating automobile interior parts.
- the present applicant has proposed an activator for a hydraulic transfer film that can also be applied to high-grade or ultra-high-grade hydraulic transfer that cannot be achieved by a conventional general-purpose ultraviolet curable resin composition (see Patent Document 4). ).

- the decorative layer obtained in this manner is UV-cured over the entire surface including the outer surface, and therefore the surface protection function by UV curing is surely imparted to the decorative layer itself. For this reason, it is possible to sufficiently handle high-grade and ultra-high-grade hydraulic pressure transfer that requires vibrant design like Motoki's feeling, and there are a wide variety of print patterns on transfer films that have accumulated in the past. In addition to being able to cope with it, it is compatible and compatible with various facilities in the current hydraulic transfer processing line.

- the activator according to Patent Document 4 can improve physical properties such as the strength and chemical resistance of the decorative layer formed on the surface of the article by hydraulic transfer, and can improve the initial adhesion to the article surface. Can improve the light resistance to some extent and maintain the adhesion, but, as already mentioned, if you try to further improve the adhesion, including the light resistance adhesion, There was a tendency for the strength and chemical resistance of the layer to decrease, and it was difficult to satisfy both the physical properties and adhesion of the decorative layer.
- a non-reactive resin such as an acrylic polymer is added to the ultraviolet curable resin composition (see Patent Documents 5 and 6).
- Patent Document 5 is a technique for suppressing the fluidity of the transfer layer by adding a non-reactive component such as polymethacrylate to the active energy ray-curable resin composition that is the transfer layer of the transfer film.

- the ink dissolving power is lowered, it is possible to ensure the film strength and prevent the shrinkage failure, but the adhesiveness is lowered.
- the viscosity is linked to the adhesiveness, the film strength, and the shrinkage, and it is required to combine the balance of the adhesiveness, the film strength, and the shrinkage with a preferable viscosity. Therefore, when it is difficult to achieve such a balance with only a bifunctional monomer, by adding a predetermined amount of a leveling agent, the adhesiveness, film strength and shrinkage can be optimized, and a good ink can be obtained. It is possible to achieve a good balance between the penetrability and the coating property.
- the leveling agent is preferably added in an amount of 0.01 to 0.1% by weight based on the entire ultraviolet curable resin composition (photopolymerizable oligomer + photopolymerizable monomer + photopolymerization initiator + non-reactive resin).

- the photopolymerization initiator is for initiating the photopolymerization reaction of the photopolymerizable oligomer and the photopolymerizable monomer, and the blending ratio thereof is 5 to 10% by weight when it is less than 5% by weight. If the photopolymerization reaction does not proceed sufficiently and defects such as poor curing occur and the amount exceeds 10% by weight, free radicals are likely to occur in the decorative layer when the cured decorative layer is exposed to ultraviolet rays. This is because the shrinkage of the decorative layer becomes remarkable, and as a result, the light-resistant adhesion decreases.
- the photopolymerization initiator in order for the ultraviolet curable resin composition to dissolve and penetrate the dried and solidified ink, is composed of a surface curable photopolymerization initiator and an internal curable photopolymerization initiator. Preferably both are included.
- the internally curable photopolymerization initiator is suitable for use when the printing pattern contains black ink.
- the blending ratio of the internal curing type photopolymerization initiator is preferably 10 to 90% by weight of the total photopolymerization initiator.
- the surface-curable photopolymerization initiator can preferentially shrink only the surface of the decoration layer to form fine irregularities on the surface of the decoration layer, and can impart a matte effect.
- a hydroxyketone system can be used
- the internal curable photopolymerization initiator for example, an acylphosphine oxide system can be used.
- the non-reactive resin used in the present invention has a function of achieving both the strength and chemical resistance and adhesion of the decorative layer, and therefore the strength and resistance of the decorative layer can be improved by applying the UV curable resin composition to the printing pattern. It is possible to improve chemical properties and adhesiveness as well as light-resistant adhesiveness at the same time. That is, when a non-reactive resin is added, the non-reactive resin is dispersed in the sea-island state within the printed pattern, and the shrinkage of the decorative layer is reduced and the adhesion between the cured coating of the decorative layer and the surface of the article is improved.
- the curing shrinkage of the decoration layer induced by free radicals generated in the cured coating of the decoration layer is alleviated, so that the light-resistant adhesion is also improved.
- this non-reactive resin is not added, especially when trying to increase the strength of the decorative layer imparted by the photopolymerizable monomer, the adhesion of the decorative layer imparted by the photopolymerizable oligomer is reduced, and both characteristics are reduced. Difficult to maintain.
- the blending ratio of the non-reactive resin is set to 2 to 10% by weight.
- the non-reactive resin is not particularly limited as long as it can realize the above action, but an acrylic polymer is particularly preferable.
- the molecular weight of the acrylic polymer is preferably from 50,000 to 10,000, particularly preferably from 60,000 to 80,000.
- the non-reactive resin such as an acrylic polymer used in the present invention
- a solvent so as to be uniformly dispersed in the ultraviolet curable resin composition. It is preferable.
- This solvent may be removed after the acrylic polymer is uniformly dispersed in the ultraviolet curable resin composition, or may be used as a coating agent while leaving the solvent in the ultraviolet curable resin composition. Even in the case, the ink activation is performed by the photopolymerizable monomer (bifunctional monomer) of the ultraviolet curable resin composition.
- This solvent is added for the purpose of dissolving the non-reactive resin (acrylic polymer) and uniformly dispersing the non-reactive resin in the UV-curable resin composition. Therefore, this solvent is used for the UV-curable resin composition.
- the photopolymerizable monomer is used in such an amount that it does not inhibit the activation of the printing pattern (solubility) and addition amount.
- the fundamental difference between the solvent-based activator and the non-solvent activating component of the UV curable resin composition is that the solvent component volatilizes after application in the former activator, so that the plastic state due to reproduction of the ink adhesion is aged over time.
- the latter activator reproduces the adhesion of the ink with the photopolymerizable monomer component that does not volatilize, so that the depopulated state of the ink does not change.
- Such an action is not significantly impaired even if a specific amount of solvent is present within the range of the photopolymerizable monomer of the present invention.
- the amount of the solvent for such purpose is 5 to 50% by weight based on the whole UV curable resin composition (photopolymerizable oligomer + photopolymerizable monomer + photopolymerization initiator + non-reactive resin). is there.
- UV-A A light resistance-imparting agent such as HALS may be added at a predetermined blending ratio.
- the amount of UV-A added is in the range of 0.5 to 1.5% by weight with respect to the entire ultraviolet curable resin composition (photopolymerizable oligomer + photopolymerizable monomer + photopolymerization initiator + non-reactive resin).
- the reason for this is that if the amount added is less than 0.5% by weight, it does not contribute to the improvement of the light-resistant adhesion, and if it exceeds 1.5% by weight, the adhesion is lowered.
- the addition amount of HALS is preferably in the range of 1.5 to 3.5% by weight because, if this addition amount is less than 1.5% by weight, it does not contribute to the improvement of light resistance. This is because if it exceeds 5% by weight, the adhesiveness and the light-resistant adhesiveness are lowered.
- UV-A and HALS commercially available products can be used as appropriate.
- the weight% which is the addition amount of these components is outside the range of 100 weight% of the ultraviolet curable resin composition.
- the viscosity of the coating agent is preferably 1000 CPS (25 ° C.) or less from the viewpoint of coating properties. Then, in view of the matting effect and the appropriate viscosity, the amount of matting agent added is the entire UV curable resin composition (photopolymerizable oligomer + photopolymerizable monomer + photopolymerization initiator + nonreactive resin). ) To 5 to 20% by weight is preferred. If it is less than 5% by weight, a sufficient matting effect cannot be obtained, and if it exceeds 20% by weight, the viscosity of the coating agent becomes high and coating becomes difficult.
- the non-reactive resin may induce thermal polymerization of the ultraviolet curable resin composition, particularly when a matting agent such as resin beads is used in combination. May be noticeable.
- the photopolymerizable components photopolymerizable oligomer and photopolymerizable monomer
- the non-reactive resin are stored in such a manner that they do not coexist. Can avoid this phenomenon.
- a composition containing a photopolymerizable component as a main component and not containing a nonreactive resin is stored as liquid A
- a composition containing a nonreactive resin and containing no photopolymerizable component is stored as liquid B. It is preferable that the liquid A and the liquid B are mixed and used when the coating agent is used.
- the photopolymerization initiator and additives may be blended in either liquid A or liquid B. Since the variation in blending can be reduced and the characteristics of the activator can be easily adjusted by the blending ratio of liquid A and liquid B, a composition containing only non-reactive resin is designated as liquid A, and is non-reactive.
- the resin is a B liquid.
- the liquid B is preferably stored in a state in which it is dissolved in the minimum solvent necessary for uniformly dispersing the non-reactive resin.
- the reactive resin may be stored in a state insoluble in a solvent, and may be dissolved in the solvent at the time of mixing.
- the ultraviolet curable resin composition 62 used in the present invention preferably has a viscosity of 10 to 500 CPS (25 ° C.). That is, when the viscosity (25 ° C.) is less than 10 CPS, the ratio of the photopolymerizable monomer is too large, and sufficient film properties cannot be obtained. Subsequent wiping tests for solvents such as xylene do not give good results. On the other hand, if it exceeds 500 CPS, the proportion of the photopolymerizable monomer is too small to sufficiently penetrate the entire dry ink of the print pattern 40, and the ink adhesion is not reproduced well.
- the viscosity of the coating agent is higher than the viscosity of the coating agent previously disclosed in Patent Document 4 by the present applicant. This is because the amount of coating is increased and a slight amount of solvent is added. Does not interfere with solubility.
- CPS in the viscosity of the ultraviolet curable resin composition is an abbreviation for centipoise as described in Patent Document 4, and the numerical value in this specification is a B-type viscometer (model BM) manufactured by Tokyo Keiki Co., Ltd. ).
- the ultraviolet curable resin composition 62 is required to have an ink solubility of 7 or more in terms of SP value for the same reason as described in Patent Document 4. That is, when the solubility of the ultraviolet curable resin composition itself has an SP value of 7 or more, it becomes close to the solubility of the ink composition of the print pattern, and therefore sufficient ink dissolving power can be exhibited. If the ink solubility is less than 7 in terms of SP value, the printed pattern 40, that is, the decorative layer 44, is transferred to the article 10 after the hydraulic transfer, even though the ink adheres to the dried ink of the printed pattern 40 and can be restored. It becomes difficult to adhere to the surface.
- the preferred range of the SP value of the activator of the present invention is the lower limit value “7” lower than “10” which is the lower limit value of the SP value of the conventional activator (Patent Document 4).
- the SP value is in the range of less than 7 to 10, it is possible to obtain ink solubility to the extent that there is no practical problem. This is due to knowledge.
- Examples 1 to 14 and Comparative Examples 1 to 5 Hereinafter, specific examples 1 to 16 of the present invention will be described in comparison with comparative examples 1 to 5.
- Specific blending ratios of the components in these examples and comparative examples are as shown in Tables 1 to 3. In these tables, the blending ratio is% by weight.
- the compounding amount of the non-reactive resin is a solid content conversion value
- the solvent addition amount is a value including the solvent in the Ubic polymer.
- a photoinitiator what mixed the hydroxyketone type
- Leveling agent for UV coating with polysiloxane skeleton (BYK-UV3500 ("BYK” is a registered trademark) manufactured by Big Chemie Japan Co., Ltd.) is used, and hydroxyphenyltriazine (HPT) UV absorber is used as UV-A.
- HPT hydroxyphenyltriazine
- UV-A hydroxyphenyltriazine
- the light stabilizer a hindered amine (HALS) light stabilizer was used.
- a 10 cm ⁇ 20 cm ⁇ 3 mm ABS resin flat plate (TM20 manufactured by UMG ABS Co., Ltd.) was used as the transfer article, and the UV curable resin composition corresponding to the transfer article was used.
- a decorative layer having a predetermined pattern was formed by the hydraulic transfer method shown in FIG.
- the printing pattern of the transfer film had a thickness of 3 ⁇ m, and the coating agent of the present invention was applied to the thickness of 10 ⁇ m by the Miyabar method.
- evaluation method for each evaluation item The evaluation method is described below for each evaluation item in the evaluation results of Tables 1 to 3.
- “ ⁇ ” is “excellent”, “ ⁇ ” is “good”, and these are desirable results for implementation, and “x” is “impossible” and is not desirable for implementation. Indicates that there is.
- Adhesion The light-resistant adhesion at the time of exposure to ultraviolet rays, which is a severe evaluation condition for adhesion, was evaluated.
- This evaluation uses a xenon fade meter (SX75) made by Suga Test Instruments, which is a light-resistant irradiator under the conditions of a black panel temperature of 89 ° C, humidity of 50%, and ultraviolet irradiance: 100 W / m 2 (wavelength range: 300 to 400 nm).
- the article to be tested (article with decoration layer) was exposed to ultraviolet light, and the peeled state was observed by a cross-cut test (according to the former JIS K5400-8.5) for each test piece in which the integrated light quantity was changed to evaluate the light-resistant adhesion. .
- the integrated light quantity was “over 125 MJ” “ ⁇ ”, “75-125 MJ” “ ⁇ ”, “less than 75 MJ” was determined as “ ⁇ ”.
- the coating agent (activator) placed in a sealed container was stored at 50 ° C. for 6 weeks, and when it was taken out from the container and coated on a transfer film, a coating with good coating properties was marked with “ ⁇ ”, A sample that was thickened but could be applied was judged as “ ⁇ ”, and a product that was difficult to coat due to significant thickening was judged as “x”.
- Examples 1 to 16 are not excellent in all characteristics, but there is no practical problem.
- Comparative Examples 3 to 5 are photopolymerizable oligomers.
- the blending ratio of the photopolymerizable monomer and the blending ratio of either the hexafunctional oligomer or the bifunctional oligomer constituting the photopolymerizable oligomer are out of the predetermined range of the present invention (see claims 1 and 2). Therefore, since at least one of the three characteristics is impossible and cannot be put into practical use, the basis of the blending ratio of each component of the present invention can be understood.
- Example 11 and Examples 1 and 12 in which the blending amount of the polyfunctional oligomer is the same but the blending of the photopolymerizable monomer is changed, a part of the photopolymerizable monomer is converted into the polyfunctional monomer. It can be seen that the mechanical strength of the film is further improved by replacing with. Furthermore, from the results of Example 12 and Example 16, when the polyfunctional monomer exceeds 10% by weight, the blending ratio of the bifunctional monomer is decreased, and hence the adhesion is decreased due to the influence of the decrease ink solubility by the bifunctional monomer. Since a tendency is seen, it turns out that it is preferable that the compounding ratio of a polyfunctional monomer shall be 10 weight% or less.
- Example 16 in Table 2 is an example in which the amount of the solvent is 50% by weight, which is considerably higher than that of the other examples.
- the ultraviolet curable resin composition in the coating agent of the present invention provides a multifunctional oligomer that imparts mechanical and chemical properties of a decorative layer formed by hydraulic transfer of a printing pattern, and light-resistant adhesion of the decorative layer.
- Bifunctional oligomers polyfunctional monomers that give the strength of the decorative layer, bifunctional monomers that have solubility to restore the adhesion of the printed pattern, and physical properties (strength and chemical resistance)
- a non-reactive resin such as an acrylic polymer that has the function of achieving both adhesiveness, so that the decorative layer has excellent strength, chemical resistance and light resistance due to the application of UV curable resin composition to the printing pattern.
- the excellent adhesion including adhesion can be improved at the same time, and the practical performance and quality are enhanced, so the industrial utility is improved.

本発明において、紫外線硬化樹脂組成物に用いられる光重合性オリゴマーは、光化学作用によって更に硬化し得るポリマーであって、光重合性不飽和ポリマーと呼ばれたり、ベースレジンや光重合性プレポリマーと呼ばれたりしており、アクリル系オリゴマー、ポリエステル系オリゴマー、エポキシアクリレート系オリゴマー、ウレタンアクリレート系オリゴマー等の何れかを単独又は任意に組み合わせて使用することができる。本発明に用いられる光重合性オリゴマーは、多官能オリゴマーと2官能オリゴマーを含み、多官能オリゴマーは、印刷パターンを水圧転写して得られる装飾層の機械物性(膜の機械的強度等)及び化学特性(耐薬品性等)、更には耐光性の如き装飾層内にある多官能オリゴマーの硬化物の分子構造に起因する諸特性を装飾層に付与し、2官能オリゴマーは、装飾層の密着性を付与する。多官能オリゴマーは、目的の装飾層の機械物性及び化学特性が得られれば特に限定しないが、光照射時の適度な光重合反応性(反応速度)とオリゴマーの粘度に起因する紫外線硬化樹脂組成物の塗工性とのバランスを考慮して6官能オリゴマーが好ましく、この6官能オリゴマーの具体的成分としては、ジペンタエリスリトールヘキサアクリレート、ソルビトールヘキサアクリレート等の公知のものを使用することができる。また、6官能オリゴマーと他の3官能以上の多官能オリゴマーを併用してもよい。2官能オリゴマーは、目的の密着性が得られれば特に限定しないが、耐光密着性を向上させる場合には、直鎖状のアクリル化アクリレート等が好ましく、例えば、ダイセル・サイテック株式会社製EBECRYL767等を使用することができる。更に、密着性に加えて他の機能を付加できる2官能オリゴマーを用いてもよい。
多官能オリゴマーと2官能オリゴマーとは、紫外線硬化後の装飾層の機械物性と密着性のバランスに応じた配合割合とし、具体的には、光重合性オリゴマーの配合割合25~56重量%のうち、多官能オリゴマーの配合割合は、12~40重量%、2官能オリゴマーの配合割合は、7~16重量%であることが好ましい。多官能オリゴマーが12重量%未満であると、密着性は向上するが膜の機械強度が不十分となる場合があり、40重量%を超えると、膜の機械強度は高くなるが密着性が低下する場合があるので好ましくない。また、2官能オリゴマーが7重量%未満であると、膜の機械強度は高くなるが密着性が不十分となる場合があり、16重量%を超えると、密着性は向上するが膜の機械強度が不十分となる場合があるので好ましくない。
光重合性モノマーである2官能モノマーは、光重合性オリゴマーを希釈する役割を果たしつつ、乾燥固化している印刷パターン(インク)を溶解する溶解性を有して印刷パターンに付着性を付与するとともに、紫外線硬化時には2官能モノマー自体が硬化反応して、装飾層自体に硬化性を付与するのに寄与する。
2官能モノマーの具体例としては、ジプロピレングリコールジアクリレート、1.6-ヘキサンジオールジアクリレート、トリプロピレングリコールジアクリレート、PEG600ジアクリレート、PO変性ネオペンチルグリコールジクリレート、変性ビスフェノールAジアクリレート、エキシ化ビスフェノールAジアクリレート、トリシクロデカンジメタノールジアクリレート、PEG400ジアクリレート、テトラエチレングリコールジアクリレート、トリエチレングリコールジアクリレート、ポリエチレングリコールジアクリレートなどの公知のものがあり、これらを単独または複数組み合わせて使用することができる。本発明において、2官能モノマーとしては、1.6ヘキサンジオールジアクリレート、シクロヘキシルアクリレート、ジプロピレングリコールジアクリレートが好ましく、インクへの浸透性と溶解力、更に好適なSP値を考慮すると、1.6ヘキサンジオールジアクリレート、ジプロピレングリコールジアクリレートが好ましい。
既に述べたように、2官能モノマーの一部を多官能モノマーに置換して、多官能モノマーに由来する機能を付加することができ、特にこの置換多官能モノマーが4官能モノマーであると、装飾層の強度を一層向上させることができる。4官能モノマーの具体的成分としては、ペンタエリスリトールテトラアクリレート、ペンタエリスリトールエトキシテトラアクリレート、ジトリメチロールプロパンテトラアクリレート等が掲げられるが、本発明の効果が得られるものであれば公知のものを使用することができる。この4官能モノマーの配合割合は、光重合性モノマー(2官能モノマー)の配合率33~65重量%のうち、10重量%以下とすることができる。4官能モノマーが10重量%を超えると、2官能モノマーの配合量が減少しすぎて、2官能モノマーによるインク溶解性が減少して密着性が低下し、更に、光重合性オリゴマーや4官能モノマーに起因する膜特性との良好なバランスをもとれなくなるので好ましくない。
光重合性オリゴマーと光重合モノマーとの配合割合をそれぞれ25~56重量%、33~65重量%としたのは、上記したそれぞれの成分が付与する特性がバランスよく維持され、この配合割合を外れると、所望のすべての特性を良好に得ることができなくなるからである。
塗布剤の粘度とインク溶解性とは、主に紫外線硬化樹脂組成物中の2官能モノマーによって調整されるが、2官能モノマーを多くすると、紫外線硬化樹脂組成物の粘度が低くなるとともにインク溶解力が高くなるため、硬化後の物品への塗膜密着性は向上するが、膜強度の低下や収縮不良を誘発し、逆に、2官能モノマーを少なくすると、紫外線硬化樹脂組成物の粘度が大きくなるとともにインク溶解力が低くなるため、膜強度の確保と収縮不良の防止を確保することができるが、密着性が低下する。このように、粘度は、密着性及び膜強度、更には収縮性と連動しており、好ましい粘度でありながら、密着性、膜強度や収縮性のバランスと兼ね備えることが要求される。そのため、2官能モノマーのみでこのようなバランスをとることが困難である場合には、所定量のレベリング剤を添加することによって、密着性、膜強度と収縮性を最適化しつつ、良好なインクへの浸透性と塗工性をバランスよく達成することができる。レベリング剤の添加量は、紫外線硬化樹脂組成物全体(光重合性オリゴマー+光重合性モノマー+光重合開始剤+非反応性樹脂)に対して0.01~0.1重量%が好ましく、0.01重量%未満であると、最適な光重合性モノマーの配合範囲を有しても紫外線硬化樹脂組成物に十分な塗工性が得られずに、印刷パターンの均一な活性化を達成できない不具合が発生し、また0.1重量%を超えると、紫外線硬化樹脂組成物の流動性が高くなりすぎて、物品に転写した紫外線硬化前の状態において、未硬化の活性化塗膜(印刷パターン)が流動してエッジに収縮皺が発生し、縮み不良という不具合が発生する。このようなレベリング剤としてはシリコーン系が好ましい。
光重合開始剤は、光重合性オリゴマー及び光重合性モノマーの光重合反応を開始させるためのものであり、その配合割合を5~10重量%としたのは、5重量%未満であると、光重合反応が十分に進まないで硬化不良等の不具合が発生し、10重量%を超えると、硬化後の装飾層が紫外線に暴露された場合に、装飾層内でフリーラジカルが生じ易くなって装飾層の収縮が顕著になり、その結果耐光密着性が低下するからである。
本発明において、紫外線硬化樹脂組成物が乾燥固化しているインクを溶解して浸透するようにするため、光重合開始剤は、表面硬化型光重合開始剤と内部硬化型光重合開始剤との両方を含んでいるのが好ましい。内部硬化型光重合開始剤は、印刷パターンが黒インクを含んでいる場合に用いるのに好適である。両方の光重合開始剤を含む場合には、内部硬化型光重合開始剤の配合割合は、光重合開始剤全体の10~90重量%であるのが望ましい。表面硬化型光重合開始剤は、装飾層の表面のみを優先的に収縮させて装飾層の表面に微細凹凸を形成させて艶消し効果を付与することができる。表面硬化型光重合開始剤としては、例えばヒドロキシケトン系を用いることができ、また内部硬化型光重合開始剤としては、例えばアシルホスフィンオキサイド系を用いることができる。
本発明に用いられる非反応性樹脂は、装飾層の強度や耐薬品性と密着性とを両立させる機能を有し、従って紫外線硬化樹脂組成物の印刷パターンへの塗布によって装飾層の強度や耐薬品性と密着性、更には耐光密着性を同時に向上することができる。即ち、非反応性樹脂を添加すると、印刷パターン内で非反応性樹脂が海島状態に分散し、装飾層の硬化収縮を緩和して装飾層の硬化塗膜と物品の表面との密着性が向上し、また、硬化後に紫外線暴露環境や加熱環境下に曝された時に、装飾層の硬化塗膜内で生じるフリーラジカルによって誘起される装飾層の硬化収縮を緩和するため、耐光密着性も向上する。もし、この非反応性樹脂を添加しないと、特に、光重合性モノマーが付与する装飾層の強度を高めようとすると、光重合性オリゴマーが付与する装飾層の密着性を減殺し、両方の特性を維持することが難しい。非反応性樹脂の配合割合を2~10重量%としたのは、2重量%未満では、上記の収縮緩和効果が得られず、密着性や非反応樹脂添加に起因する耐光密着性が低下し、また10重量%を超えると、耐薬品性能が低下するからである。この非反応性樹脂としては、上記の作用を具現することができれば、特に限定されないが、特にアクリルポリマーが好ましい。また、アクリルポリマーの分子量(ゲルパーミエーションクロマトグラフフィー測定による重量平均分子量)は、50000~10000が好ましいが、特に好ましいのは、60000~80000である。
本発明に用いられるアクリルポリマーの如き非反応性樹脂が高粘度の状態又は半固体や固体の態様である場合には、紫外線硬化樹脂組成物に均一分散させるために溶剤に溶いた状態で添加することが好ましい。この溶剤は、紫外線硬化樹脂組成物にアクリルポリマーを均一分散させた後に、除去してもよいし、紫外線硬化樹脂組成物内に溶剤を残したまま塗布剤として使用してもよいが、後者の場合においても、インク活性化は、紫外線硬化樹脂組成物の光重合性モノマー(2官能モノマー)により行われる。この溶剤は、非反応性樹脂(アクリルポリマー)の溶解とこの非反応性樹脂の紫外線硬化樹脂組成物への均一分散を目的に添加されるものであり、従ってこの溶剤は、紫外線硬化樹脂組成物の光重合性モノマーによる印刷パターンの活性化を阻害することがない特性(溶解力)と添加量で使用されることを理解すべきである。溶剤系活性剤と紫外線硬化樹脂組成物の非溶剤性活性化成分との根本的な相違は、前者の活性剤では塗布後に溶剤成分が揮発するため、インクの付着性の再現による可塑状態が経時的に変化するが、後者の活性剤(本発明)では揮発することがない光重合モノマー成分でインクの付着性を再現するので、インクの過疎状態が変化することがないことである。このような作用は、本発明の光重合モノマーの配合量範囲であれば、特定量の溶剤が共存していても著しく損なわれない。このような目的の溶剤の添加量は、紫外線硬化樹脂組成物全体(光重合性オリゴマー+光重合性モノマー+光重合開始剤+非反応性樹脂)に対して、5重量%~50重量%である。
本発明の紫外線硬化樹脂組成物塗布剤を転写フィルムに塗布し印刷パターンを水圧転写、硬化して得られる物品表面における装飾層の密着性を維持しつつ耐光性を向上させるために、UV-AやHALSの如き耐光性付与剤を所定の配合割合で添加してもよい。UV-Aの添加量は、紫外線硬化樹脂組成物全体(光重合性オリゴマー+光重合性モノマー+光重合開始剤+非反応性樹脂)に対して、0.5~1.5重量%の範囲が好ましく、その理由は、この添加量が0.5重量%未満であると、耐光密着性の向上に寄与せず、1.5重量%を超えると、密着性の低下を招くからである。HALSの添加量は、1.5~3.5重量%の範囲が好ましく、その理由は、この添加量が1.5重量%未満であると、耐光密着性の向上に寄与せず、3.5重量%を超えると、密着性や耐光密着性の低下を招くからである。UV-AやHALSは、市販の製品を適宜使用することができる。なお、これらの成分の添加量である重量%は、紫外線硬化樹脂組成物の100重量%の範囲外である。
装飾層の全体に霞が掛かったような意匠表現が行えるように、この紫外線硬化樹脂組成物に樹脂ビーズを添加してもよい。ガラスビーズであると、その大きな比重によって沈降してしまうので、PET樹脂やアクリル樹脂やウレタン樹脂のビーズが好ましい。これらの艶消し剤を添加した場合においては、塗工性の観点から塗布剤の粘度は、1000CPS(25℃)以下であるのが好ましい。そして、艶消し効果と適正な粘度の観点とを考慮すると、艶消し剤の添加量は、紫外線硬化樹脂組成物全体(光重合性オリゴマー+光重合性モノマー+光重合開始剤+非反応性樹脂)に対して5~20重量%が好ましい。5重量%未満だと、十分な艶消し効果が得られず、20重量%を超えると塗布剤の粘度が高くなり、塗工が困難となるので好ましくない。
本発明の塗布剤において、非反応性樹脂は、温度が高くなると、紫外線硬化樹脂組成物の熱重合を誘発することがあり、特に、これは、樹脂ビーズ等の艶消し剤を併用した場合に顕著となることがある。このため、塗布剤が高温貯蔵を伴って使用される場合には、光重合性成分(光重合性オリゴマーと光重合性モノマー)と非反応性樹脂とが共存しない形態で貯蔵することによってこのような現象を回避することができる。すなわち、光重合性成分を主成分として、非反応性樹脂が配合されていない組成物をA液として貯蔵し、非反応性樹脂を含み、光重合性成分が配合されていない組成物をB液として貯蔵し、塗布剤の使用時にA液とB液とを混合して使用するのが好ましい。光重合開始剤や添加物(耐光性付与剤、レベリング剤及び/又は艶消し剤)はA液とB液のどちらに配合しても構わないが、A液とB液の混合における構成成分の配合ばらつきを小さくすることができ、かつA液とB液の配合割合による活性剤の特性調整が容易にできることから、非反応性樹脂のみが配合されていない組成物をA液とし、非反応性樹脂をB液とすることが、特に好ましい。
なお、非反応樹脂のA液への均一分散性を確保するために、B液は、非反応性樹脂を均一分散するに必要最低限の溶剤に溶いた状態で貯蔵することが好ましいが、非反応性樹脂は、溶剤に溶かない状態で貯蔵し、混合時に、溶剤に溶いてもよい。このような分液化の形態とすることで、本発明の課題を解決しつつ、長期における品質安定性も図られて、高品質の製品を得ることができる。
本発明に用いられる紫外線硬化樹脂組成物62は、10~500CPS(25℃)の粘度を有するのが好ましい。即ち、粘度(25℃)が10CPS未満であると、光重合性モノマーの割合が多過ぎて、充分な塗膜物性が得られないので、渾然一体化して紫外線硬化した装飾層であっても、その後のキシレン等の溶剤に対するワイピングテストで、良好な結果が得られない。逆に、500CPSを超えると、光重合性モノマーの割合が少な過ぎて、印刷パターン40の乾燥インク全体に充分に浸透せず、インクの付着性が良好に再現しない。なお、塗布剤の粘度は、本出願人が先に特許文献4で開示した塗布剤の粘度よりも高いが、これは、塗布量を増加し、また若干の溶剤を添加していることでインク溶解性を妨げることはない。
紫外線硬化樹脂組成物の粘度における「CPS」とは、特許文献4で述べたように、センチポアーズの略称であり、本明細書の数値は、株式会社東京計器社製のB型粘度計(形式BM)を用いて計測した結果である。
光重合性モノマーが3~30CPS(25℃)の粘度とSP値で9以上のインク溶解度とを有していると、10~500CPS(25℃)の粘度とSP値で7以上のインク溶解度とを有する紫外線硬化樹脂組成物を調合し易くなる。
紫外線硬化樹脂組成物62は、SP値で7以上のインク溶解度を有することが要求されるが、その理由は、特許文献4で述べたのと同じである。即ち、紫外線硬化樹脂組成物自体の溶解度がSP値で7以上を有することは、印刷パターンのインク組成物の溶解度に近づけることになるので、充分なインク溶解力を呈することができることになる。インク溶解度がSP値で7未満であると、印刷パターン40の乾燥インクに浸透してインクの付着性を復元することができても、水圧転写後、印刷パターン40、即ち装飾層44が物品10の表面に付着し難くなる。
なお、本発明の活性剤のSP値の好ましい範囲を、従来の活性剤(特許文献4)のSP値の下限値である「10」よりも低い下限値「7」としたのは、本発明の活性剤を発明する過程で、印刷パターンのインク組成物と活性剤との相性などによっては、SP値が7~10未満の範囲でも、実用上問題ない程度のインク溶解性が得られる、という知見によるものである。
上記の「SP値」は、同様に、特許文献4で述べたように、溶解性パラメータ(Solubility parameter)の略称であり、スー(K.W.SUE)とクラーク(D.H.CLARKE)が発表している濁度滴定法によるもので、この濁度滴定法は、「Journal of Polymer Science PARTA-1,Vol.5,1671-1681(1967)に記載されている。
以下に、本発明の具体的な実施例1乃至16を比較例1乃至5と比較しながら説明する。これらの実施例及び比較例の各成分の具体的配合割合は、表1乃至3に示されている通りである。なおこれらの表において、配合割合は重量%である。
表1乃至3の評価結果における各評価項目毎にその評価方法を以下に述べる。なお、評価方法において「◎」は、「優良」、「○」は、「良」で、これらは、実施に望ましい結果であり、また「×」は、「不可」で実施上好ましくない結果であることを示す。
「膜の機械的強度」は、被試験物品の膜(装飾層)の強度を鉛筆硬度試験(JIS K5600-5-4準拠)で測定して評価したものであり、「H以上」は、「◎」、「HB~F」は、「○」、「HB未達」は、「×」と判定した。
密着性の厳しい評価条件である紫外線暴露時の耐光密着性について評価した。この評価は、ブラックパネル温度89℃・湿度50%、紫外線放射照度:100W/m2(波長範囲300~400nm)の条件で、耐光性照射器であるスガ試験機製キセノンフェードメーター(SX75)を使用して被試験物品(装飾層付き物品)を紫外線暴露し、積算光量を変えた試験片毎にクロスカット試験(旧JIS K5400-8.5準拠)で剥離状態を観察して耐光密着性評価した。同じ積算光量毎に10個の試験片について試験したところ、1個でも剥離が発生したときの積算光量が「125MJ超」を「◎」、「75~125MJ」を「○」、「75MJ未満」を「×」と判定した。
10%のオレイン酸含有の試験液(溶媒は石油ベンジン)をスポイトで0.2ml抽出し、これを被試験物品の凹凸意匠面に滴下した後、80℃のオーブン内に4時間、24時間それぞれ放置し、被試験物品を取り出し、室温まで自然冷却し、被試験物品の表面の油分を拭き取った。その後、セロテープ(登録商標)で被試験物品の膜(装飾層)を引き剥がして付着性を評価した。この評価において、装飾層の外観変化(膨れ等)及び剥がれ全くない場合を「◎」、外観変化はあるものの剥がれが観察されない(製品として問題がない)場合を「○」、外観変化と剥がれがともにある(製品として使用することができない)場合を「×」と判定した。
密閉容器内に入れた塗布剤(活性剤)を50℃において6週間放置して保管した後、容器から取り出して転写フィルムに塗工したときに、塗工性が良好なものを「◎」、増粘しているが塗工可能な状態のものを「○」、著しい増粘により塗工困難なものを「×」と判定した。
(1)表1を見ると、本発明の実施例中、実施例1による物品は、膜の機械強度、耐光密着性、耐薬品性のいずれにも優れ、すべての特性をバランスよく実現できたことが解る。
(2)一方、表3を見ると、比較例1による物品は、塗布剤に非反応樹脂を使用していないため、膜の機械強度と耐光密着性とを両立することができないことが解り、また、比較例2及び3による物品は、塗布剤の非反応樹脂が本発明の所定の範囲(請求項1参照)を超えているため、装飾層の耐薬品性が劣化していることが解る。
(3)表1乃至表3を見ると、実施例1~16は、すべての特性が優れているわけではないが、実用上支障がなく、他方、比較例3~5は、光重合性オリゴマー及び光重合性モノマーの配合割合や、光重合性オリゴマーを構成する6官能オリゴマー又は2官能オリゴマーのいずれかの配合割合が、本発明の所定の範囲(請求項1及び2参照)から外れているため、3つの特性の少なくとも1つの特性が不可であり、実用化することができないことから、本発明の各成分の配合割合の根拠が解る。
(4)また、多官能オリゴマーの配合量が同じであるが光重合性モノマーの配合を変えた実施例11と、実施例1及び12の結果から、光重合性モノマーの一部を多官能モノマーで置き換えることにより、膜の機械強度が一層向上することが解る。
更に、実施例12と実施例16の結果から、多官能モノマーが10重量%を超えると、2官能モノマーの配合割合が減じるため、2官能モノマーによるインク溶解性の減少の影響によって密着性が減じる傾向が見られることから、多官能モノマーの配合割合は、10重量%以下とすることが好ましいことが解る。
なお、本実施例では、多官能モノマーとして4官能モノマーを適用した例のみを示したが、5官能モノマーや6官能モノマーを適用した場合であっても光重合による分子結合が3次元的に形成されるため、同様に膜の機械強度が向上されるので、これらの多官能モノマーも本発明に含まれることは言うまでもない。
(5)再び、表1を見ると、塗布剤に艶消し剤が添加されて形成された実施例2による製品についても、実施例1と同様にいずれの特性も優れていることが解る。
(6)表2の実施例16は、溶剤を他の実施例よりも相当に多い50重量%とした例であるが、溶剤の添加量がこの50重量%を超えると、印刷パターンへの塗工後に溶剤の揮発が進み、インク可塑化作用が経時的に低下して、水面上での装飾層の伸展をコントロールするのが難しくなる傾向が見られ、また、物品への転写、硬化後ならびに耐光密着性評価のクロスカット試験において、密着性が低下したり、膜の機械強度を除く他の特性が実用に耐えることができなくなったりする場合もあるため、溶剤は50重量%以下にすることが好ましいことが解った。
(7)塗布剤(活性剤)の貯蔵性は、比較例2、3を除き他の実施例及び比較例で良好であったが、特に、実施例14、15のように、塗布剤を光重合性成分と非反応性樹脂成分とに分けた2液化の態様で貯蔵すると、高温環境下での貯蔵性が良好となることが解る。なお、比較例2、3による塗布剤の貯蔵性が悪いのは、非反応性樹脂の添加量が多いため、紫外線硬化樹脂組成物の熱重合の誘発度合いが増したためと考えられる。
(8)最後に、表には示されていないが、実施例と比較例の全てにおいて、いずれも印刷パターンへの塗工の際に、筋引きやハジキ等の不具合がなく、良好な塗工性を有していたことが解っている。
