Description of the Invention [Technical Field] The present invention relates to a polarizing plate and a method of manufacturing the same. [Prior Art] In recent years, display devices for displaying characters, images, and the like have been widely used as liquid crystal display devices. Such a liquid crystal display device generally includes two polarizing plates, a liquid crystal cell composed of a glass substrate disposed therebetween, a transparent electrode, a color filter, a light distribution film, and a liquid crystal. Generally, a polarizing plate used in a liquid crystal display device is one-sided or double-sided on a polarizing film (polarizer) in which an extended aligning polyvinyl alcohol (hereinafter, also referred to as PVA)-based sheet adsorbs iodine or a two-color dye. A protective film such as a triethylenesulfonated cellulose (hereinafter also referred to as TAC)-based film is bonded to the adhesive layer. In such a polarizing plate, a polarizing plate has been proposed, in which a polarizing plate is bonded to a protective film of at least one side of a polyvinyl alcohol-based polarizing film via a polyvinyl alcohol-based adhesive layer, and the adhesive layer is contained. a polyvinyl alcohol-based adhesive of a water-based epoxy compound, wherein the ratio of the water-soluble epoxy compound to the polyvinyl alcohol-based resin in the adhesive is (5 to 50) / 100 (solid weight ratio) (refer to Kaiping 09-2 5 8 023). Further, in this document, the triacetyl cellulose which is alkalized on the surface of the protective film is also described. According to the technique described in the above document using a water-based adhesive and a TAC-based protective film, the moisture of the above-mentioned adhesive can be evaporated by a TAC-based protective film having a high moisture permeability to cure the adhesive. Therefore, the polarizing plate can be obtained by a relatively simple manufacturing process of -5-200839324. Further, since the water-based adhesive has high adhesion to the TAC-based protective film, a polarizing plate having excellent adhesive strength can be obtained. However, the TAC-based protective film has a high moisture permeability and has a problem of low moist heat resistance. In other words, in an environment of high temperature and high humidity such as a vehicle, deformation or the like may occur, and it is difficult to maintain high polarization performance. Therefore, a method of using a cyclic olefin-based resin film (cycloolefin-based resin film; hereinafter, also referred to as a COP-based resin film) having a low moisture permeability in place of the TAC-based protective film has been proposed. For example, a polarizing plate has been proposed which is characterized in that one of the polarizing films composed of a polyvinyl alcohol-based resin contains a polyester-based ionic monomer-type urethane resin and a glycidyl group. Laminating a olefin-based resin film on the first adhesive layer of the aqueous composition of the compound, and laminating the cellulose acetate on the other side via a second adhesive layer having an aqueous composition different from the first adhesive layer A film (refer to Japanese Laid-Open Patent Publication No. 2005-20845-6). Further, a method for producing a polarizing plate has been proposed in which a polarizer and a protective film of a polarizer are adhesively laminated, characterized in that at least an aqueous emulsion and a polyvinyl alcohol and a polyisocyanate compound are contained, and the use is adjusted to B. The viscosity of the viscometer (2 (TC) is an aqueous urethane-based adhesive of 0.03 to 1 Pa_s, and the polarizer and the protective film are wet-laid (refer to Japanese Patent Publication No. 2004-3 7 84 1 Further, in this document, it is described that the protective film is composed of a thermoplastic saturated norbornene-based resin. 200839324 [Disclosure of the Invention] The technique described in Japanese Patent Laid-Open Publication No. 2005-208456, Since the moisture of the water-based adhesive can be evaporated by the cellulose acetate-based film having a high moisture permeability, the polarizing plate can be obtained in a relatively simple manner, similarly to the technique described in JP-A-H09-2 58 023. However, since the cellulose acetate-based film having a high moisture permeability on one side has a problem that moisture-heat resistance is insufficient, or the adhesion between the first adhesive layer of the water-based adhesive and the cycloolefin-based resin film is not high. According to the technique described in Japanese Laid-Open Patent Publication No. 2004-37841, since the protective film on both sides of the polarizer is made of a thermoplastic saturated norbornene-based resin, a polarizing plate having good moist heat resistance can be obtained. When a protective film having a low moisture permeability is used, it takes a long time to evaporate the water of the aqueous urethane-based adhesive of the water-based adhesive, and the manufacturing process becomes complicated compared with the case of using a TAC-based film. Further, since the protective film composed of the thermoplastic saturated norbornene-based resin is hydrophobic, the problem of insufficient adhesion to the aqueous adhesive is still present. Further, when manufacturing a polarizing plate, an excellent resistance to wafer cutting is sought. That is, the polarizing plate is generally obtained by cutting the laminated sheet for the polarizing plate into a desired size, but when the cutting is performed, peeling occurs at the cut portion (the end portion after cutting) (adhesive agent) The problem of the lack of corners of the layer. This peeling system not only reduces the polarizing performance of the peeling portion, but also promotes the moisture absorption of the polarizing plate, causing deformation under high temperature and high humidity, etc. Further, the polarizing plate is exposed to liquid crystal display. The panel is adhered by an adhesive. When it is 200839324, there are bubbles in the polarizing plate and the liquid crystal display panel, and the polarizing plate may be deformed. At this time, in order to reuse the liquid crystal display panel, the polarizing plate can be removed from the liquid crystal display panel. Peeling, take the step of bonding a new polarizing plate (reproduction step). However, when the adhesion between the protective film forming the polarizing plate and the polarizer is weak, when the polarizing plate is peeled off, the protective film and the polarizer may be peeled off. At this time, the protective film remains on the liquid crystal display panel, and the manufacturing efficiency is lowered by the step of peeling off the protective film. Therefore, the adhesive used to bond the protective film to the polarizer is used in the manufacture of the polarizing plate. In terms of remanufacturing, it is also sought to exert a strong adhesive strength (peel strength) between the polarizer and the protective film. Moreover, the polarizing plate is intended to be less warped. That is, the polarizing plate is for preventing the liquid crystal cell from being damaged by ultraviolet rays, and it is necessary to add an ultraviolet absorber or an ultraviolet absorbing layer in addition to one of the protective films of the polarizing plate. Therefore, when the adhesive is cured in the production of the polarizing plate, substantially only the side of the protective film from which the ultraviolet absorbing agent is not applied is irradiated with light, and the irradiation strength of the adhesive layer having two layers is inferior. As a result, the polarizing plate formed by lamination generates warpage, which may affect the subsequent workability. The present invention has been made in view of the above-described background, and the manufacturing steps can be easily and quickly manufactured, and the object of the invention is to provide a polarizing plate which is resistant to wafer cutting property (no peeling at the time of cutting) and excellent in moist heat resistance, and a method for producing the same . Moreover, an object of the present invention is to provide a polarizing plate having a high adhesiveness (peeling strength) between the protective film and the adhesive layer, and a method for producing the same, and the method for producing the same, and the present inventors have focused on the above problems. RESULTS 'Fa-8-200839324 The polarizing film and the protective film are adhered to each other using a radiation curable composition containing a specific component, and the polarizing film and the protective film can be manufactured in a short period of time, and the polarizing resistance such as wafer cutting property and moisture heat resistance can be manufactured in a short time. The board finally completes the invention. That is, the present invention provides the following [1] to [10].

For the component (C), 'if the key salt shown by the formula (4) is used, compared to the other anion species such as SbF', A polarizing plate having a smaller warpage can be obtained. Further, in the case of the component (C), if the iron salt represented by the formula (4) is used, the radiation curable composition can be prepared without using the component (B). Obtain a polarizing plate with a small warpage. In the polarizing plate In manufacturing, the protective film of one of them has the property of absorbing ultraviolet rays, and the curing of the adhesive is performed by light irradiation from one side of the polarizing plate. Adhesion of photoacid generator using other anionic species such as SbF6_ The agent has sufficient adhesion, but the curing speed is fast. Therefore, when the adhesive is used as a polarizing plate, the reason why the polarizing layer absorbs light or the like is that the curing speed of the adhesive layer of the two layers is likely to be poor. When a photoacid generator using PF6_ as an anion is used, it is an appropriate hardening rate, so that the difference in the hardening speed of the adhesive layer having two layers becomes small, and as a result, the warpage becomes small. a key salt of an anion represented by the formula [MXq(OHK].

In the present invention, it is preferred that the solvent is not contained in terms of maintenance of the working environment, environmental load, and the like. Further, the transmittance of the light having a wavelength of 550 nm in the case of the radiation curable adhesive composition having a thickness of 200 μm is preferably 70% or more, more preferably 80% or more. If the above transmittance is less than 70%, the transmittance of the polarizing plate itself is also lowered, which is not preferable. Further, the radiation curable composition is preferably filtered by a filter or the like. Next, a polarizing plate and a method of manufacturing the same according to the present invention will be described with reference to the drawings.

In FIG. 1, the polarizing plate 1 is composed of a polyvinyl alcohol-based polarizing film 2, an adhesive layer 3, 4 formed on both sides (bottom surface and upper surface) of the polarizing film 2, and an adhesive layer 3 laminated thereon. The protective films 5 and 6 formed on each of the single faces of 4 (specifically, the lower surface of the adhesive layer 3 and the upper surface of the adhesive layer 4). [Polarizing film] -32- 200839324 A polyvinyl alcohol-based polarizing film (hereinafter also referred to as a PVA-based polarizing film) can be used as the polarizing film. The PVA-based polarizing film system can be generally used as a polarizing film, and the polyvinyl alcohol-based film adsorbs iodine or a dichroic dye to extend the alignment. The thickness of the polarizing film is not particularly limited, but is limited to, for example, 〇 〇 4 〇 ι η [adhesive layer] φ The adhesive layer is a cured layer formed by curing the radiation curable composition by radiation. When the adhesive layer is formed by using the radiation curable composition, excellent wafer cut resistance can be obtained, and even if the protective film is either COP or TAC, the protective film and the adhesive layer can be adhered. The strength is excellent. The thickness of the adhesive layer is not particularly limited, but is limited to, for example, 0 · 0 1 to 5.0 μm 〇 [Protective film] The protective film may be, for example, an acetate resin of triethyl fluorenyl cellulose.

That is, the configuration of the polarizing plate is preferably the above (2) and (3), and more preferably the above (3). According to the configuration of the above (2) and (3), a COP-based film having a low moisture permeability can be used as a protective film, so that a polarizing plate excellent in moisture-heat resistance can be obtained. In the present invention, one of the upper and lower protective films is a protective film against the ultraviolet absorber, and the other protective film is an ultraviolet-permeable protective film. In the above-mentioned ultraviolet ray protective film, when the polarizing plate is disposed on both sides of the liquid crystal cell, ultraviolet rays from the outside can function to protect the liquid crystal cell. The UV-resistant protective film can be suitably formulated with an ultraviolet absorber. The transmittance of light having a wavelength of 380 nm of the ultraviolet ray protective film is, for example, 10% or less. 保护i: The protective film of the ultraviolet ray permeability is irradiated with _ ray (light illuminating) from the side of the protective film to illuminate the ray. The hardening composition is hardened. The ultraviolet ray-permeable protective film does not contain an ultraviolet ray absorbing agent, or has a wavelength of 38 〇 nm of a protective film that contains 'the degree of hardening of the radiation curable composition by the protective film. The transmittance of light-34-200839324 is, for example, 60% or more. A phase difference can also be provided in the protective film. Further, the thickness of the protective film is not particularly limited, but is limited to, for example, 10 to 200 μm χ °. The protective film system can also be subjected to various surface treatments before application of the radiation curable composition.
