The support (4) is protected from the uncured ultraviolet curable type 期间 in the period until the end of use. Fig. 1 is a schematic cross-sectional view showing the step of forming the light-shielding pattern on the two sheets by using the ultraviolet curable adhesive (') of the present invention. (4) in the figure is the ultraviolet curable adhesive layer of the present invention, which is shown in Fig. 2, and is in the ultraviolet curable adhesive layer u雔. The B-series of the branch body is for use: the period before the support A is protected by a protective film for the adhesive layer which is not hard X-ray film. (8) is a step of peeling the support B of the adhesive layer transfer sheet 10 97106759 8 200842032, and the (6) of the next step is to arrange the lens sheet 2 of the cylindrical lens 21 side by side, The ultraviolet curable adhesive layer n is bonded to the flat surface on the back side of the lens surface. In the next step (4), by exposure from the lens side of the lens sheet -20, the exposed portion of the lacquer-hardened adhesive layer n loses its adhesiveness. An exposed portion (non-adhesive portion) 11a and an unexposed portion (adhesive portion) are formed on the ultraviolet-curable adhesive layer u. In the next step (4), the support A is peeled off, and the next step (1) is to separately prepare a light-shielding layer such as a light-shielding layer having a light-shielding layer 31 adhered to the ultraviolet-curable type. Adhesive layer u. Then, as in step (g), by peeling off the light-shielding layer transfer sheet 3, since the exposed portion (non-adhesive portion) Ua region of the ultraviolet-curable adhesive layer 11 has no adhesive force, Therefore, the light shielding layer 31a is peeled off together with the support c, and since the unexposed portion (adhesive portion) 11b of the ultraviolet-curable adhesive layer 11 has an adhesive force', the light shielding layer 31b remains in the ultraviolet-curable adhesive layer U. In the unexposed portion (adhesive portion) 11b region, that is, the light shielding layer 31 is transferred only to the unexposed portion of the fragrant ultraviolet curable adhesive layer U. Thereby, any opaque pattern formed on the non-lens surface of the lenticular sheet 20 can be obtained. Although a light-shielding pattern is formed on a lens sheet, a mask may be used to form a pattern on a adherend such as a film or glass. The present invention relates to such a step. purple The wire-curable adhesive layer is formed by the composition of the ultraviolet-curable adhesive layer, which has the following characteristics: = the adhesiveness before the light', and the exposed portion loses the adhesiveness. The cured adhesive layer transfer sheet is coated with a UV-curable adhesive layer on the support a, and is adhered to the lens sheet immediately after drying (step (c)). When the ultraviolet curable adhesive layer transfer sheet of the present invention is used for a projection type television screen, it is a material for forming a light-shielding pattern on the non-lens surface of the lens sheet. The adhesive layer of the adhesive layer transfer sheet and the outer-line hardening type adhesive layer are at least a (meth) acrylate having a mercapto group or a repellent group, a binder resin composed of an organic polymer, and a photopolymerization initiator. After the coating is dried, the film thickness in the uncured state is 5 // m to 35 // m. The (meth) acrylate used in the above-mentioned external and external hardening type adhesive layer has one or more. (methyl A photopolymerizable photosensitive resin represented by an ultraviolet curing type of an acrylonitrile group. Examples thereof include urethane (meth) acrylate, epoxy (meth) acrylate, and polyester (曱). Any of various compounds such as acrylates, polymers, oligomers or monomers, and various functional groups. In the present invention, among these, in particular, a phenyl group having a hydroxyl group or a carboxyl group is used. It is preferable to use a fluorenyl acrylate monomer or an oligomer or a mixture of two or more kinds of other (meth) acrylates, and when forming a pattern on the lens sheet, the light-shielding pattern forming property and the light-shielding pattern are formed. The adhesion of the various lens sheets is superior, in particular, the weight ratio of the (meth)acrylic vinegar having a phenyl group and a hydroxyl group or a carboxyl group to the ultraviolet curable adhesive layer, if it is the ultraviolet curable adhesive layer From 20 to 70% by weight, it is more preferable in terms of light-shielding pattern formability and adhesion to various lens sheets for forming a light-shielding pattern. The material of the lens sheet is not limited to the extent that the acrylic resin-based lens sheet is particularly excellent in the (four) properties of the ultraviolet-curable adhesive layer.

When forming a screen form, if it is used for a long period of time, the ultraviolet hard acid layer is peeled off from the non-lens surface of the lens sheet, and it is impossible to use it as a mouth. Therefore, it is preferable to improve the adhesion of the ultraviolet curing type adhesive layer. , The adhesion between the UV-curable adhesive layer and the various lens sheets. When it is not necessary to form a pattern on various lens sheets (for example, glass), it is preferable to further improve the adhesion between the glass and the ultraviolet curable adhesive layer. A bonding resin composed of an organic compound is blended into the ultraviolet-curable dust adhesion layer, and is associated with a bonding agent for forming a pattern, and is a dispersion medium of various additives, and has a (fluorenyl) acrylic acid. The adhesion of the ester is accompanied by a dose of 1 agent, and the cohesive force of the ultraviolet-curable adhesive layer is increased, and the cohesive force of the hardened adhesive layer of the outer-line hardened type is maintained and maintained. For example, a phenol resin, an acrylic resin, a urea-based sulphate, a polyester resin, an alkyd resin, a rolling resin, an anthrone resin, a furan resin, and a poly The vinyl chloride resin, 97106759 11 200842032 The polyurethane resin, and the derivative of the resin, etc., may be used alone or in combination of two or more. The adhesive resin composed of the organic t compound is made of a wide variety of acrylic thermoplastic resins having excellent transparency, and by precisely selecting the type and the glass transition temperature, it is possible to increase the adhesion of the ultraviolet curable adhesive layer. The cohesive force of the ultraviolet curable adhesive layer can also increase the cohesive force of the ultraviolet curable adhesive layer in an unhardened state to maintain the holding force. In the present invention, it is preferable that the ultraviolet curable adhesive layer is not hardened, and the holding force is preferably 3 mm or less. Here, the term "retention force" refers to a value obtained by measuring according to Jis^ 0237 in accordance with the weight of 1 kg and one hour. When the holding force is 4 mra or more, when it is stored in a wound form after coating, it causes a cause of bleeding out of the coating layer from the end face of the support of the adhesive layer, which tends to cause deterioration of subsequent steps. 13 A = Photopolymerization initiator is an additive which can cure the ultraviolet curable pressure-sensitive adhesive layer by ultraviolet rays, and examples thereof include a benzoin system, a benzyl ketal system, a benzophenone system, and an acetophenone system. , benzoin, thioxanthone, phosphine oxide, depending on the wavelength of the exposure device, the light time, the performance of the t-curing layer, the long-term performance stability of the special system, etc. Alternatively, the system can be used alone or in combination with 2 insertions of J △ or more. And if necessary, it is also possible to add, for example, a thioxanthone compound, 2-sulfur gas, a 2-sulfatobenzothiazole, a 2-sulfhydrylbenzopyrene, a pyromazole, ^ ^ Temple Fang Xiang thiolated character sensitizer, chain transfer agent. The amount of the photopolymerization initiator to be added is preferably a photo-curable photopolymerizable photosensitive resin, and it is preferable to add a heavy denier, and the upper limit is not impaired in performance. In the ultraviolet curable adhesive layer of the present invention, a (meth) acrylate having a phenyl group and a trans group or a carboxyl group, and an adhesive resin composed of an organic polymer, depending on the solid content ratio, are used. It is 30/70~70/30, and must be dried after drying, and the film thickness of the uncured state is 5/zm~35//m. If the ratio of (mercapto) acrylate having a phenyl group to a hydroxy group or a carboxyl group is too large, the cohesive force of the coating film becomes small, and the coating layer is easily damaged due to a slight force from the outside, or when it is 2 When the ultraviolet ray-curable pressure-sensitive adhesive layer 2 is placed between the sheet supports, the ultraviolet ray-curable pressure-sensitive adhesive layer composition is oozing out from the end portion of the support body when the holding force of the coating layer is reduced. Causes problems such as workability day $. ^The ratio of the binder resin composed of the organic polymer is too large, and the adhesion of the ultraviolet-curable adhesive layer becomes small. For example, when a light-shielding pattern is formed on the lens sheet, the ultraviolet-curable adhesive layer and the lens sheet are lowered, and the occurrence of defects is caused. The situation can be pure. In addition, if the ratio of the phenyl group to the hydroxyl group or the carboxyl group is used, the ratio between the phenyl group and the hydroxy group or the carboxyl group is the same as that of the binder resin composed of the organic polymer. Deterioration, resulting in more difficult to handle or unusable, the machine will take the base and the base or sulfhydryl (meth) acrylate, and the ratio of: "Do not constitute a bonding resin optimized, will It is an important matter: the film thickness of the UV-curable adhesive layer is in the unhardened state, if UV: 01' will become the cause of the pattern resolution (four), on the contrary, the film thickness of the ir-type ir-type adhesive layer exceeds In the case of 35 (4), the second cause in the adhesive layer is the cause of the decrease in the resolution of the pattern, the increase in the weight, and the increase in the cost of the transfer sheet. 97106759 13 200842032 The term "peeling balance" as used herein refers to Figure 1 (a). In the case where the ultraviolet curable adhesive layer is interposed between the two sheets of the support A and the support B, the peeling strength a between the support A and the uncured ultraviolet curable adhesive layer will reach the support. B and unhardened UV hard The peeling strength of the adhesive layer is more than 4 times, and is weaker than the adhesion between the ultraviolet curable adhesive layer and, for example, the lens sheet, and the peeling strength of the support C coated with the light shielding layer and the light shielding layer is strong. Between the UV-curable adhesive layer and the lens sheet, the balance between the layers is established. When the conditions are not satisfied, when the support is peeled off, there is no need to peel off. In addition, the "peel strength" is based on JIS K 6854-2, and the resistance value at the time of peeling is performed in accordance with the peeling speed of 300_/min, the peeling angle of 180°, and the width of 25 mra. The term "state of long-term performance stability" refers to the pattern formation property and the adhesion to various lens sheets when the UV-curable adhesive layer transfer sheet is produced and stored in 23% or 5% of the environment. Other properties, can be used for more than 1 year, or in the promotion test, when stored in a 〇 environment, the shading pattern formation, and the adhesion between the various lens sheets. Kean It can be used for more than one month. In addition, 'in the UV-curable adhesive layer composition, it is suitable for coating. It can also be added with thinner. For example, · methanol, ethanol, butanol, methyl ethyl ketone , ethyl acetate, toluene, methyl sialo, ethyl cyanidin, butyl cyanidin, methyl isobutyl ketone, butyl cyproterone acetate, etc., without prejudice to the object of the present invention, If necessary, it can be appropriately added and formulated using a coating agent such as a plasticizer, an antioxidant, an anthrone compound, 97106759 200842032 antifoaming agent, adhesion promoter, filler, anti-collapse agent, stabilizer, and various additives for dilution with pigments.诮 and various additives must greatly affect the coating liquid properties and long-term performance stability of the UV-curable adhesive layer composition, so care must be taken. Further, the term "coating suitability" means whether the coating property suitable for coating and the necessary quality can be easily exhibited when the ultraviolet curable adhesive layer composition is applied by a processing machine (4). For example, when #coated on a biaxially stretched polyethylene terephthalate film, 'if the surface tension of the coating liquid of the adhesive layer is significantly higher, the film and the coating liquid will bounce off, and the benefit The method obtains the coated surface of the target. However, by adding a suitable leveling agent to the coating liquid in a small amount, the target coating φ can be easily obtained, that is, it can be removed without deteriorating other properties, and the coating suitability is excellent. The supporting system of the external hardening type adhesive layer can be stably maintained as long as the adhesive layer, for example, an acetate film, a polyvinyl chloride film, a polyethylene film, a polypropylene film, a polycarbonate film, a polyparaphenylene. Ethyl dicarboxylate film or the like. In particular, it is a biaxially-oriented polyterephthalic acid which is excellent in heat and water stability, and which is excellent in workability and exposure at the time of application for forming an ultraviolet-curable adhesive layer, and operability at the time of transfer. The ethylenediester film is preferred. The thickness of the support is not particularly limited. When 20# m to 150 # m, wrinkles, air bubbles, and the like are less likely to occur during transfer, and workability is excellent. Further, in the present invention, in order to make the transfer property of the ultraviolet curable adhesive layer tend to be easy, a release treatment by subjecting the support to a release treatment may be employed. 97106759 15 200842032 A substrate. Such a release-treated substrate is provided, for example, on a support p, in addition to a commercially available release substrate such as an anthrone-based resin or a tetrahydrofuran resin. Any one of an ethyl phthalate resin, a melamine resin, a fluorine resin, an anthrone resin, a polyester resin, a polyolefin resin, or an alkyd resin, or a coating of the mixture The dried release layer is applied to a dry thickness of 5/zm or less (preferably 2 or less). μ

(4) The line is stronger than the cut body. Release treatment 97106759 200842032 This pair of stupid acid bismuth acrylate film is made into a UV-curable adhesive sheet. π曰~ Furthermore, the 'shading layer transfer sheet is prepared to be colored. A pigment (carbon black) and a propylene/acid/styrene emulsion are mixed with a light-shielding layer composition, coated on a PET film, and dried to form a thick layer. The support body of the adhesive layer transfer sheet is peeled off to the non-lens surface of the lens sheet, and the ultraviolet-curable adhesive layer transfer sheet is lm/min and the roll temperature is 5 〇. 线, line pressure i〇kg/cm The conditions are applied by lamination and lamination. Then, after irradiating an appropriate amount of ultraviolet rays from the lens surface by using a parallel beam ultraviolet exposure device, the light-shielding layer transfer sheet is lm/min according to the method shown in FIG. After the roller heating and the line pressure of 1 〇kg/cm are applied, the bonding is performed. The light-shielding layer transfer sheet was peeled off and black stripes were formed. Then, various evaluations as described below were carried out, and as a result, it was found that the performance was satisfactory. [Example 2] • In addition to the benzene containing Example 1 The methacrylate of the base group and the carboxyl group was changed to 26% by weight, the trimethylol propyl triacrylate was changed to j 〇 by weight%, and the binder resin composed of the organic polymer was changed to 36% by weight, and the rest was implemented as The ultraviolet curable adhesive layer transfer sheet was produced in the same manner as in Example 1. As a result of evaluation and evaluation, although the resolution of the light-shielding pattern was slightly inferior to that in Example 1, it was found that the performance was substantially satisfactory. [Example 3] The coating film thickness of Example 1 was changed to 5 // m after drying, and the UV-curable adhesive layer transfer sheet was produced as in Example 1, and the result of evaluation was performed by 97106759 18 200842032, and a light-shielding pattern was obtained. Although the resolution and the peeling balance are deteriorated, 'but it is not up to the extent that it is unusable, and it can satisfy the performance of other items. [Example 4] • In addition to changing the coating film thickness of Example 1 to 35"m after drying outer, The UV-curable adhesive layer was prepared as in Example 1. As a result of evaluation, although the resolution of the light-shielding pattern was very good, the retention of the adhesive layer and the long-term performance stability were still poor, but still _Unsupplied to the extent of use. [Example 5] The methyl acetoacetate containing phenyl and decyl group of Example 1 was changed to 15 weight % 1 and the trimethylol propyl triacrylate was changed to 3 5% by weight, the adhesive resin composed of the organic polymer was changed to 27% by weight, and the ultraviolet-curable adhesive layer transfer sheet was produced as in Example 1, and the adhesion of the coating film was obtained as a result of evaluation. It is lowered, and the shading pattern resolution # is also deteriorated, but it has not reached the level of unusability, and it can roughly satisfy other items. [Example 6] Except that the methacrylate containing a phenyl group and a carboxyl group of Example 1 was changed to 50% by weight%, and the binder resin composed of an organic polymer was changed to 22% by weight. The UV-curable adhesive layer transfer sheet was produced in the same manner, and as a result of evaluation, the peel strength of the support Α and Β was slightly increased and the peeling balance was deteriorated, but it was not yet unusable, and it was able to satisfy other requirements. Item performance. 97106759 19 200842032 [Comparative Example 1] Except that the phenyl group-containing thiol acrylate having the phenyl group and the thiol group of Example 1 was changed to 〇% by weight, and the trishydroxypropyl propyl acrylate was changed to 36% by weight, the rest The ultraviolet curable adhesive layer transfer sheet was obtained as in Example 1. However, both the resolution and the peeling balance of the light-shielding pattern were deteriorated, and it was not safe to use as a finished product. [Comparative Example 2] The same as the example except that the methacrylate containing a phenyl group and a carboxyl group of Example 1 was changed to 重量% by weight, and the binder resin composed of the organic polymer was changed to 62% by weight. The ultraviolet curable adhesive layer transfer sheet was obtained in general, but the peeling balance was deteriorated, and the light shielding pattern could not be formed. [Comparative Example 3] The methyl acrylate vinegar containing phenyl and silk was changed to % by weight except that the binder resin composed of the organic polymer was changed to 15 weights, and the rest were as in Example 1. The UV-curing type of the adhesive is generally obtained. The cohesive force of the externally hardened adhesive layer is reduced, and the peeling balance and retention are deteriorated, which is not a good finished product. [Comparative Example 4] The coating film thickness of 6 & Example 1 was changed to Z after drying, and the ultraviolet curable adhesive layer was obtained in the same manner as in Example 1 [Comparative (four) resolution (four) difference' (four) good Finished product. The external coating (4) Houling became the first example to obtain the ultraviolet curing type adhesive layer. 97106759 20 200842032 The p-shading pattern has good resolution and peeling balance, but the adhesion layer has the strength and coating suitability. Very poor, it is quite difficult to get a stable finished product. The evaluation results of the above respective examples and comparative examples are shown in Table 1 * below. In addition, the evaluation method is as follows. [Evaluation method] (1) The shading pattern resolution is good) ◎ > 〇 > gt > Χ (Differential Φ • The black stripe after the shading pattern is formed visually evaluates the linearity of the line. • One means that the shading pattern cannot be obtained.
