For example, 'When UV rays are used. When the hardening type of the adhesive is applied to the outer line having a wavelength of from 350 nra to about 380 nm, it is initially hardened in tens of seconds and hardened to have moderate elasticity after several knives. The ultraviolet curable adhesive is composed of a prepolymer and a single The body and photopolymerization initiator (for example, photocationic polymerization 321135 9 200947053 initiator) have a small thermal expansion and a precise temperature stability under temperature cycling. Moreover, 'because the remainder (4) can be followed by high precision, : The water rate maintains high quality even in high-humidity and high-temperature environments. For the fat-curing adhesive such as a fat-based adhesive, for example, hydrogenated epoxy resin m epoxy resin or aliphatic epoxy resin can be cited. The above ultraviolet curing type adhesive which does not contain an aromatic ring in a molecule such as a fat does not contain water and other solvents in its composition, so that it does not exist between the polarizing film 2 and the protective film 8 and in the solvent, in the heat resistance promoting test. The film 2 is formed at the end of the polarizing plate or bubbles are formed on the bonding surface with the glass surface, and the appearance of the optical fiber layer and the optical layered body can be obtained. The coating of the ultraviolet curing adhesive is limited to, for example, The film thickness 〇.5//111 to 6/zm, preferably 丨"^ is not particularly good, the application method of the ultraviolet curing type adhesive is not specifically the method and device of the § When the generation of Yu Zhuo is hardened by ultraviolet irradiation, the light source used is a light distribution with a length of lOOrnn to 400mn. The intensity of ultraviolet radiation is determined by the composition of the slope, although it is not particularly limited, but The intensity of the wavelength in the wavelength range in which the activity of the initiator is effective is 对^ is 600mW/on2. If the intensity of ultraviolet light is less than lmW/cm2, it will become too long, if it exceeds 600mW/cm2. , because of the heat and composition of the luminaire At the time of heat generation, the irradiation time of the ultraviolet ray which causes deterioration of the polarizing film is different depending on the composition of the hardened composition. Although it is not limited to (4), it is preferably set to be strong according to the irradiation time. The cumulative amount of light represented by the product is set to 1〇 to , and the degree is 200947053 •丨' 000mJ/cm2. If the cumulative amount of light does not reach l〇mJ/cm2, the active species from the initiator will be insufficient and hardened. On the other hand, if the cumulative amount of light exceeds 1, 〇〇〇mj/cm2, the irradiation time becomes extremely long, which is disadvantageous for productivity. The laminate of the polarizing film 2 and the protective film 8 when irradiated with ultraviolet rays Although the conveyance speed is not particularly limited, it is preferably in the conveyance direction to a tension of 5 〇〇N/m, an irradiation intensity of i to 6 〇〇mW/cm 2 , and an irradiation time of 1 to 10 seconds. , the laminated body is irradiated with ultraviolet rays. Further, in the present embodiment, the polarizing film 2 is a continuous film, and the protective film 8 is a sheet film method. However, the film is a reverse film, the continuous film is a protective film, and the sheet film is a polarizing film. Further, the optical laminate can be produced by laminating the polarizing plate obtained in the above manner with at least one film selected from the group consisting of a phase difference film, a brightness enhancement film, a viewing angle improvement film, and a semi-transparent reflection plate. The invention is specifically described by the following examples, but the invention is not limited by the examples. (Example 1) An ultraviolet curable adhesive (KRX492-25 manufactured by ADEKA Co., Ltd.) was applied to a polyvinyl alcohol-based polarizing film having a thickness of i23/rm and a width of 40 mm by a coating apparatus using the apparatus shown in Fig. 1 . On one side, a sheet-like retardation film (300 mm x 400 mm, thickness 88 μm, manufactured by Sekisui Chemical Co., Ltd.) was placed thereon, and then ultraviolet rays were irradiated by ultraviolet light irradiation at a cumulative light amount of 300 mJ/cm 2 for 5 seconds. The type of adhesive was hardened to obtain a polarizing plate (irradiation wavelength: 365 nm, film thickness of the adhesive: 3 (^, 321135 11 200947053 force · 1OON/m during transportation). (Comparative Example 1) In addition to using NS300MP (LINTEC) In the same manner as in Example 制作, a polarizing plate ′ was produced in the same manner as in Example 作为, and a heat resistance promoting test was carried out as a pressure-sensitive adhesive. And the polarizing plate obtained in the comparative example i was repeatedly and repeatedly carried out in a constant temperature bath at a temperature of 85 C and a temperature of 40 ° C at intervals of 30 minutes, and heat and cooling. After performing 350 cycles of the interaction, the gas was observed. , As a result, it was found that bubbles were generated throughout the entire circumference of Comparative Example 1, but bubbles were hardly observed in the polarizing plate of Example 1. <Heat resistance test (protrusion at the end of the film)> Polarization obtained by the above Example 1 After the plate was kept in the environment of 8 51 for 250 hours, the protrusions at the ends of the sacs were observed by a confocal interference microscope (→ 2,300 by sens〇far company). As a result, the range from the end to the inside of 5_ In contrast, in the polarizing plate of Comparative Example 1, the protrusion height is 3 to 4/m.
