Description

201139585 VI. Description of the Invention: [Technical Field] [0001] The present invention relates to a photocurable adhesive (photo- for applying a polarizing element and a protective film on a polarizing plate) And a polarizing plate prepared by adhering the protective film to the polarizing element; and a method of manufacturing the polarizing plate. Moreover, the present invention also relates to an optical member and a liquid crystal display using the polarizing plate.

Device. [Prior Art] [0 0 0 2] The polarizing plate is one of the optical members constituting the liquid crystal display device. Generally, the polarizing plate is laminated in a liquid crystal display device in a state in which a protective film is laminated on both surfaces of the polarizing element. It is also known to lay a protective film on only one side of a polarizing element. 'But most of the cases are 'the other side' is not only a protective film but also a layer having other optical functions' also serves as a protective film. And stick it on it. Further, as a method for producing a polarizing element, a method of uniaxially drawing polyvinyl alcohol film dyed with dichromatic colorants is treated with boric acid, washed with water, and then dried. [0 0 0 3] Generally, after the polarized light element is washed and dried as described above, the protective film is adhered to 1003215437-0 100107985 201139585 immediately; the slave is used because of the material of the polarizing element behind the wire, and it will curl up. The problem of cracking in the direction of the defender. Therefore, after the dry polarizing element is coated with the water-based adhesive, the adhesive is used as a medium, and the two sides are covered with a fineness. Usually a 'degraded material, a thickness of (9) to (10) micron Um of a triethylenesulfonated cellulose film (ΤΗ_^ιΐυΐ(10)Η(6). [0004] Protective film made of a polarizing element and a protective film, particularly a triacetyl cellulose film The adhesives are mostly adhesives of Polyethylene type, and are also replaced by Urethane _ adhesive. For example, in the Supplementary Document No. 7-Recommendation No. 17 A vinegar oligomer (previously fine) is used as an adhesive to adhere a high water content polarizing element and an ethylene acetylcellulose protective film such as a triethyl fluorene cellulose film. [0 0 0 5] On the other hand, since the water vapor transmission rate of triethyl fluorenyl cellulose is high, the resin film is used as a component, and under moist heat, for example, temperature 7 (TC) In the case of a relative humidity of 90%, there is a problem of causing deterioration, etc. It has also been proposed that a resin film having a lower transmittance than a triethyl cellulose film is used as a protective film, and the related problems are solved. Method, for example, with amorphous polyolefin (am〇rph〇US p〇1y The 〇lefin) resin is widely known as a film for protecting 100107985 1003215437-0 4 201139585. In particular, Japanese Laid-Open Patent Publication No. Hei 6-511-No. A saturated resin sheet of norb〇rnene is used as a protective film. [0 00 6] In the past, a protective film having a low water vapor transmission rate was used in the device, and adhesion using hydrazine as a main solvent was often used. For example, after the protective film is adhered to a polyvinyl alcohol-based polarized 7G material using a polyvinyl alcohol aqueous solution, the solvent is dried, and the method of the so-called wet mash (10) t Lammation may not be sufficient. The problem occurred. This is a thief with a low water vapor transmission rate. It is more hydrophobic (hydiOphQbie) than the triethyl cellulose membrane. Due to the low water vapor transmission rate, the water as a solvent cannot be fully dried. ❹ 0 00 7] Therefore, JP-A-2000-321432, "Patent Document 3", proposes a protective film made of a polyethyl alcohol-based polarizing element and a thermoplastic raw borneol _ resin. The poly-axis agent is not available; however, it takes a long time to: The problem of hardening 'and the adhesion is not enough - enough. [0 00 8] On the other hand, it is known that it can be on both sides of the polarizing element. Protection of the different views of the lining 100107985 1003215437-0 201139585 The film, for example, JP-A-2002-174729, "Patent Document 4", proposes: On the surface of the polarizing element made of polyethylene-tree, there is no crystal form The ship membrane made of dilute hydrocarbon surface fat is on the other side, and the lion and the amorphous crystal canned grease are unique _ 'such as triethyl cellulose secret film; special open 2005-2嶋6 bulletin "Special 5 5" towel, on one side of a polarizing film made of erythritol lysine, laminated with a cyclic first olefin (cycl 〇 olefin) resin using an aqueous first adhesive containing a specific polyurethane resin as a medium On the other surface, an aqueous second adhesive different from the first adhesive is adhered, for example, an aqueous solution of a polyvinyl alcohol-based resin is used as a medium, and an ethylene glycol-based cellulose resin film is laminated. The amorphous polyolefin-based resin referred to in the above-mentioned Patent Document 4, and the cycloolefin-based resin referred to in the aforementioned Patent Document 5, have the same as the norbornene or its derivative, dimethylene. A unit of a monomer (m〇n〇mer) made of a polycyclic cycloolefin (dimethanooctahydronaphthalene) leaves like a ring-opened polymer. In the case of a double bond, it is desirable to add a nitrogen-based thermoplastic resin thereto. [0010] Further, in Patent Document 6 of Japanese Laid-Open Patent Publication No. 2004-245925, an adhesive which does not contain 100107985 1003215437-0 6 201139585 3 ep% xy resin as a main component has been disclosed, and A method of attaching a polarizing agent to a protective film by irradiating the adhesive with an energy ray to polymerize the cation. The epoxy resin agent disclosed herein is effective in the use of a variety of translucent fats, such as amorphous hydrocarbon lysine and a cellulose resin, in the polarizing element, but in the form of a propylene glycol (type) resin. In the case of acrylic resin as a protective film, B's adhesion is inevitably insufficient and well known. [Patent Document] [Patent Document 1] [Patent Document 1] Japanese Laid-Open Patent Publication No. JP-A No. H06-321117 [Patent Document 5] JP-A-2005-208456 [Patent Document 6] JP-A-2004-245925 SUMMARY OF INVENTION [Problems to be Solved by the Invention] [00 12] Solve the problem of the polarizing element of the polyethylene _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ However, if you simply lengthen the dry nucleus, it is prone to discoloration due to aging aging (heat deter tiQn). Here, it is desirable to reduce the drying temperature so that the polarizing element does not have the problem of silking, and it will be considered. In order to fully wire, it is necessary to lengthen the length of the drying furnace and invest in equipment (4). Too big _ question. In addition, when different types of protective films are adhered to both sides of the polarizing element, since the thermal shrinkage rates of the protective films are different, they become adhered to the polarizing elements in the different orbital states of the two sulfurs, and are dried after drying. At the time, the curl is liable to occur on the polarizing element, which causes such a problem. [0 0 13] In order to improve the related problems, a method of applying dry 1 aminat ion is also considered, but since it has an adhesive suitable for dryness, the viscosity is extremely high, and the polarizing element is physically The weaker problem is that the method of attaching the polarizing element and the protective film is limited by applying an adhesive to the protective film and then adhering to the polarizing element. With this method, if the coated surface of the adhesive adheres to the foreign matter before the adhesion, the foreign matter cannot be hidden. After the adhesive is applied, the foreign matter is used as a starting point to generate bubbles between the adhesive layer and the polarizing element, which becomes a bright spot (bright spot) The cause of the defect.

In order to obtain a smooth coated surface having a thickness of 5 μm or less, the adhesive must have a reduced viscosity; however, once the adhesive is lowered in viscosity, a decrease in the adhesive force tends to occur. Therefore, the inventors of the present invention have found out that by using a specific photocurable adhesive, the low viscosity is formed, and the polarizing element and the resin selected from the group consisting of polyester resin, polycarbonate resin, and acrylic resin are displayed.

Therefore, in this state, in general, the case where the protective film is superposed on one surface of the polarizing element on both sides; the polarizing element side and the protective film side; and the protective film is overlapped on both surfaces of the polarizing element, the protective film side of the both surfaces is used. Press the roller and the like to pressurize. Here, the material of the roll can be made of metal or rubber, and the rolls provided on both sides can be the same material or different materials. 65 100107985 1003215437-0 201139585 [0 12 8] 氺 Hardening operation As described above, the uncured photocurable adhesive acts as a medium, and the polarizing element and the protective female are attached to the test state, and the woman provides a hardening operation. In the hardening operation, the photocurable adhesive is irradiated with an active energy source, and the adhesive containing an epoxy compound or an oxetane compound is hardened, and the polarizing element and the protective film are adhered to each other. It is possible to illuminate the source line f from either the polarizing element side or the protective film side on the one side of the polarizing element. Further, when the protective film is adhered to both surfaces of the polarizing element, the active energy ray is irradiated from the protective film on either side, which is advantageous in simultaneously curing the photocurable adhesive on both sides. However, when the ultraviolet absorber is added to the protective film on either side, "for example, a cellulose resin film containing a UV absorber is used as one protective film", and when the active energy source is ultraviolet rays, usually, The other protective film that has not been blended with the ultraviolet absorber is irradiated with ultraviolet rays. As the active energy source, visible light, ultraviolet light, X-ray, electron beam or the like can be used. However, from the viewpoint of easy availability and sufficient curing rate, ultraviolet light is generally used. The light source of the active energy source is not particularly limited, but has a low-temperature mercury lamp (low pressure mercury 100107985 1003215437-0 66 201139585 (vapor) lamp) at a wavelength of 400 nanometers (nm) or less. Medium pressure mercury (vapor) lamp, high pressure mercury (vapor) lamp, ultrahigh pressure mercury (vapor) lamp, chemical lamp, black lamp (black-light lamp), microwave excitation mercury (vapor) lamp, metal halide lamp, Light-Emitting Diode lamp, etc. can be used.

D [0 13 0] The light irradiation intensity of the photocurable adhesive is determined depending on the purpose of each composition, and is not particularly limited, but the irradiation intensity of the effective wavelength range of the activated polymerization initiator is as ' UV-B "UV in the medium wavelength range of 280 to 320 nm (nm)" is more desirable than 1 to 3,000 mW/cm2 (mw/cm2). When the irradiation intensity is less than 1 mW/cm 2 , the reaction time becomes too long; on the other hand, when the irradiation intensity exceeds 3,000 mW/cm 2 , the radiant heat from the bulb and the photocurable adhesive are polymerized. When it is heated, a yellow turn of the photocurable adhesive and deterioration of the polarizing element may occur. [0 13 1] The light irradiation time of the photocurable adhesive is controlled according to each hardening composition, and is not particularly limited, but the integrated light 1 represented by the product of the irradiation intensity and the irradiation time (Integrated irradiation) ) Set at 1〇~5, 100107985 67 1003215437-0 201139585 House... Ear/cm2 (ΜΑ) is ideal. When the amount of integrated light is less than millijoules per square centimeter, the active material from the polymerization initiator (caffey species) is insufficiently produced, and the hardening of the adhesive layer may be insufficient; on the other hand, the integrated light amount exceeds 5, _ millimaterial / square __, the irradiation of ten changes is very long 'for the improvement of the yield into the forestry factor. [0 13 2] About the illuminating energy optometry hard tilting touch, the polarization of the polarizing element (degree 〇f polarizatin), transmittance (tra fine lobes) and hue (eolor phase; hue) ' It is more desirable to protect the ambiguity and choose to harden the conditions τ which do not reduce the various polarizing plates. [0 13 3] The polarizing plate obtained in this manner has a thickness of the adhesive layer of usually 5 μm or less, more desirably 2 μm or less, and more preferably 10 μm or less. [0 134] * Optical member When a polarizing plate is used, an optical member in which an optical layer that exhibits an optical function of a polarizing function is laminated on one side of the polarizing plate may be formed. The optical layer laminated on the polarizing plate for the purpose of forming an optical member is formed into a liquid crystal display device 100107985 68 1003215437-0 201139585, such as a reflective layer or a semi-transmissive type reflection. A layer, a light diffusion layer, a phase difference plate, a condensing film, a brightness enhancement film, and the like. The reflective layer, the semi-transmissive reflective layer, and the light-diffusing layer are those used in the case of forming a optical member by a semi-transmissive type or a diffused type which is not reflective, and a dual-purpose polarizing plate of the type. 〇【0 13 5】 The reflective polarizer' reflects the light incident on the viewing side, and is used in a liquid crystal display device of this type. Since the light source such as a backlight can be omitted, the liquid crystal display device can be easily changed. thin. The semi-transmissive polarizing plate is displayed in a bright type in a reflective form; in a dark place, a light source such as a backlight is used for display, and is applied to this type of liquid crystal display device. As the optical member of the reflective polarizing plate, for example, a foil made of a metal such as aluminum or a vaP〇r deposition film may be added to the protective film on the polarizing element to form a reflective layer. As an optical member of the semi-transmissive polarizing plate, for example, the reflective layer is formed as a semi-reflective coating, or a reflective sheet containing a pearl pigment and having a light transmissive property is adhered to a polarizing plate. Can be made. On the other hand, as an optical member of the diffusing type polarizing plate, for example, a method of applying a matte finish to a protective film on a polarizing plate, a method of applying a microparticle-containing resin, and a method of adhering a film containing a microparticle, A structure in which fine concavities and convexities are formed on the surface by various methods. 100107985 69 1003215437-0 201139585 [0 13 6] There is also a formation of an optical member of a polarizing plate for reflection and diffusion, for example, by providing a reflection on a fine uneven structure surface of a diffusion type polarizing plate. A method of forming a reflective layer or the like of the uneven structure can be made into such a polarizing plate. The reflective layer of the fine concavo-convex structure diffuses the incident light by diffuse reflection, and has the advantages of preventing directivity and glare, and suppressing brightness and unevenness. Further, the resin and the film containing the fine particles diffuse the incident light and the reflected light while passing through the fine particle-containing layer, and have an advantage of further suppressing the imbalance between light and dark. The reflective layer having a fine uneven structure on the reflective surface may be directly attached to the metal by steaming or piating such as vacuum deposition, ion plating, or sputtering. On the surface of the fine concavo-convex structure, it can be made. In order to form fine particles to be prepared by the surface fine uneven structure, for example, silica, alumina, titanium oxide, zirconia, tin oxide having an average particle diameter of 丄.丄30 μm can be used. Inorganic fine particles such as (tin(n) 〇xide) and indium oxide; and organic fine particles such as crosslinked or uncrosslinked polymers. [013] On the other hand, the retardation plate as the optical layer is intended to be a phase difference (eQmpensatiqn) due to a liquid crystal cell. Examples of such examples include: double-folding of various plastic stretch films, etc. 100107985 70 1003215437-0 201139585 birefringence film, discoticmesophase or nematic liquid crystal The liquid crystal layer or the like is formed on the film or the substrate which is oriented and fixed. In this case, it is preferable to use a cellulose-based film such as tridecyl cellulose to support the film substrate of the alignment liquid crystal layer. [0 13 8] Plastics which are formed into birefringent films are exemplified by polyolefins such as polycarbonate, polyethylene glycol, polystyrene, polymethyl methacrylate (poly methyl methacrylate). Methacrylate), polypropylene, etc.; polyarylate; polyamide; amorphous polyolefin resin. The stretch film may be a material treated by a suitable method such as uniaxial or biaxial; or may be adhered to the heat shrinkable film, lacking shrinkage force and/or tensile force, and making the film thicker. A birefringent film whose refractive index is controlled. Further, the 'phase difference plate' is designed for the purpose of controlling optical characteristics such as broad banding, and two or more pieces can be used in combination. [0 13 9] The light collecting plate is used for the purpose of optical path control, etc., and is used as a prism array sheet or a lens array sheet, a so-called dot sheet, or the like. , you can form. [0140] 100107985 1003215437-0 201139585 A brightness enhancement film is used for the purpose of improving the brightness of a liquid crystal display device or the like, and examples thereof include a refractive index (refractive index). Anisotropy films that are different from each other, stacked with multiple layers to make the reflectance anisotropic, such a reflective linearly polarized separation sheet; cholesteric liquid crystal polymer Orienting film or a circularly polarized separation sheet or the like which supports the oriented liquid crystal layer on the film substrate. [0141] The optical member is a semi-transmissive type reflective layer, a light diffusion layer, a phase difference plate, a condensing film, and a brightness enhancement layer according to the purpose of use. Fi ln 〇 or the like may be selected as a laminate of two or more layers, or a laminate of two or more layers. In this case, a light diffusion layer, a phase difference plate, a light concentrating plate, or a brightness enhancement film may be used. The optical layer may be separately disposed in two or more layers; and the arrangement of the optical layers is not particularly limited. [0 142] Each of the silk layers which are formed into an optical member is integrated with the polarizing plate. However, the use of _ fine, as long as the shaft is a good hybrid layer, there is no special (four) system. From the point of view of the lion Jian and the prevention of optical distortion (mail y 72 100107985 1003215437-0 201139585 distortion), etc. Agglutinant, also known as pressure-sensitive adhesive, is ideal. Viscose adhesives can be used with acrylic polymers "acrylic po" Lymer), or a compound of a silicone polymer, a polyester, a polyurethane, a polyether or the like as a base polymer; such as an acrylic adhesive, optically transparent Excellent, maintains moderate wettability and cohesion (c〇hesi〇n), excellent adhesion to substrates, weather resistance and high temperature resistance, etc., in heating or humidification (humidify) Under the conditions, foaming or peeling does not occur, and it is preferable to select such a compound.
