Description

201231598 VI. Description of the Invention: [Technical Field] [0001] The present invention relates to a photocurable adhesive (photo- used for bonding a polarizing element and a protective film on a polarizing plate) Hardening adhesive; and a polarizing plate formed by using the adhesive composition, a protective film adhered to a polarizing element; and a method of manufacturing the polarizing plate. Further, the present invention relates to an optical member and a liquid crystal display device using the polarizing plate. [Prior Art] [0002] A polarizing plate is one of optical members constituting a liquid crystal display device. Generally, a polarizing plate is laminated and protected on both sides of a polarized light 7G member, and is assembled and used in a liquid crystal display device. The case where a protective film is laid on the one-sided surface of the polarizing element is also well known 'but in most cases, the other is difficult, not only a protective film but also has other optical functions (10), and also serves as a film. Paste on it. Further, a method for producing a polarizing element is widely known in which a uniaxially stretched polyvinyl alcohol resin (um_l drawingpolyvinyl alc〇h〇1 film) film dyed with two color pigments (dich and atic colorants) is treated with an emblem. Wash with water and then dry. 3 [0003] 201231598 Attached to the piece (3) Washed and dry as described, the _ protective film is attached to the 'private because the physical strength of the first component of the dry test is weak, and the curling will cause cracking in the direction of the grain. The problem. Therefore, after drying the _ polarizer, the glaze is applied with a water-based adhesive, and immediately the adhesive is used as a medium, and a protective film is attached to both sides. Generally, the material of the protective film is a triethylenesulfonated cellulose film (tnaCety (tetra)lulQsefllm) having a thickness of 3 〇 to 120 μm ("m). [0004] The adhesion of the polarizing element and the protective film, particularly the protective film made of the triethyl cellulose film, is mostly a side polyethylene __agent, and a polyurethane (u-) type adhesive is also used instead. For example, Japanese Patent Laid-Open No. Hei 7-12-617 (Patent Document 1) discloses: a urethane oligomer (test (4) 01^) as a secret agent, a high water-containing light-receiving element and an ethylene-based fiber + U_lcellul〇se) protective film, such as triethylenesulfonyl cellulose film, adhered together. [0005] On the other hand, since the water vapor transmission rate of the divinyl cellulose (10) is very high, the resin film is used as a guarantee _ ' 'under wet heat' such as temperature 70t: In the case of a relative humidity of 9〇%, there is a problem that causes deterioration. Therefore, it has also been proposed to use water vapor to pass through the lower resin film of the triethylene sulfonate 4 201231598 cellulose film as a protective film, which is a method for solving the related problems 'for example, an amorphous polycarbonate (am〇rph〇us) T-heart (4) shaft protective film 'is widely known. Specifically, 'Specially Opened No. 51117 Bulletin 2': On at least the single surface of the resident element, riding the thermoplasticity: em〇Plastlc) saturated norbornene ( N〇rb〇r_) type resin sheet as a protective film [0 0 0 6] In the past, in the device, the adhesive which has a low water vapor transmission rate is adhered, and an adhesive using water as a main solvent, for example, polyvinyl alcohol is often used. In the aqueous solution, after the protective film is adhered to the polyethylene-sub-polarized element, the solvent is dried. The method of so-called wet 褚 ((4) LaminatiQn) may cause problems such as fresh strength and appearance that cannot be obtained. Because the water vapor transmission rate is low, it is generally more hydrophobic (hydrQphc) than the triethyl cellulose film, because the water vapor transmission rate is low, the water as a solvent cannot be sufficiently dried, and the like. [0007] Therefore, JP-A-2000-321432 (Patent Document 3) is a protective film made of a polyvinyl alcohol-based polarizing element and a thermoplastic raw borneol thin resin, and is adhered by a polyurethane-adhesive adhesive. However, there is a problem that it takes a long time to harden, and it is not enough to say enough. 5 [0008] 201231598 On the other hand, it is known that a film can be applied, for example, on the two sides of the special opening _-m72q ^ piece, and the different types of protection are applied to the arm B, and it is reported in Patent Document 4, The polarizer made of ethylene resin film is made of olefin resin, and is adhered to the amorphous form: the type of negative 椋f 匕 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 (4) The base _ _ "patent literature, the resulting thin - one surface, into the right out on the ♦ 埽 埽 _ resin -, on the 3 有 疋 polyurethane resin aqueous first adhesive as a medium, cascading The ring-like handle is still ... and the cyclo_olefin resin film is on the other side, and there is no layer-adhesive_aqueous second transfer agent, such as an aqueous solution of a polyethylene glycol resin, laminated. E-fiber special resin film. The amorphous olefin resin referred to in the aforementioned Patent Document 4, and the cycloolefin resin referred to in the aforementioned Patent Document 5, have the same properties as the norbornene or its derivative, dimethylene. A unit of a monomer (m〇n〇mer) made of a polycyclic cyclo-hydrolephthalene (dimethanooctahydronaphthalene), leaving a ring-opened polymer (ring-opened p〇) In the case of a double bond like iymer, it is desirable to add a thermoplastic resin to the hydrogen. [0010] [0010] [0010] In Japanese Patent Laid-Open No. 2004-245925, Patent Document 6, it is disclosed that an epoxy resin (epGxy as a main component) is not used as an active component, and The energy ray illuminates the adhesive to make the cation away: poly:: a method of adhering the polarizing element and the protective film. The epoxy resin axial agent disclosed herein, although an amorphous polycarbonate resin and Cellulose-based resin: The first type of permeable _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In the case of love, they must be indistinguishable and well known. ' [〇〇11] Therefore, in the choice of two dilute acid (type) resin "acrylic resin" (acrylic coffee 11), When the polyester resin (P〇1yester resin), 武 碳酸 carbonate resin rt rtxmate resin, and the low water vapor transmission rate of the amorphous hydrocarbon resin are used as the protection element of the polarizing element, the present invention The team will develop a light-hardening adhesive bond that is good for a short period of time. RESULTS 3 There was a good adhesion of the composition of the condensed glycerin of the fragrant king of the scented scented scented scented epoxy resin (Indigo rcSln) and the oxetane compound. The content of the (meta) acryiate monomer of the alicyclic structure is 5 to 25% by weight, showing extremely high adhesion and durability. To find out the above, only "Specialism 7". However, the silk production process itself is not long after the light irradiation 7 201231598, the short-time operation of the thin film processing after the irradiation can be completed, but after the film is taken up, In the case of the problem of insufficient adhesion, there is a problem in the production work. [Patent Document] [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei 7-120617 (Patent Document 2) [Patent Document 3] JP-A-2002-174729 (Patent Document 5) JP-A-2005-208456 [Patent Document 6] JP-A-2004- Bulletin No. 245925 Patent Document 7: JP-A-2010-209126 SUMMARY OF INVENTION [Problems to be Solved by the Invention] [0013] In order to solve the problem of a polarizing element of polyvinyl alcohol and a low moisture permeability by wet enthalpy Sticking-starting issues, depending on the length of the dry furnace to earn the drying time, but simply lengthen the length of the drying furnace, the capacity of the students due to heat deterioration of the polarizing element (color deterioration) of the door 8 201231598 Therefore, I hope to reduce the dryness, so that the resident Yuan will spend money on the problem, it will be transferred, __, in order to be fully _, it is necessary to lengthen the length of the drying furnace, and there is a change in the design Too big _ questions. _, in the two transfer materials of the polarizing element __ preservation of the company, due to the different shrinkage rate of the face film, the two sides of the protective film of the _ degree is not _ state and the polarized parts stick, after drying, pay At normal temperature, curling easily occurs on the polarizing element, which causes such a problem. [0014] In order to improve the phase problem, the use of dry laminati (n) to adhere to the financial method is also considered, but because it has a suitable dry thief _ meaning, its viscosity is extremely high, and the silk component has a weak female _, the method of attaching the polarizing element and the film is applied to the protective film by applying an adhesive and then adhering to the polarizing element, which is limited. With this method, if the coated surface of the adhesive adheres to the foreign matter before the adhesion, the foreign matter can not be hidden, and the sticky, with the foreign matter as the secret, the bubble between the _ layer and the polarizing element becomes a bright spot (bright spQt) Defects (the reason for her (1).

As a protective film for a polarizing element, it has been widely used in the past. Triethyl sulfhydryl The triacetyl cellul〇se film has a water vapor transmission rate of about 3.8 gm/m2/24 hours. However, in the present invention, the protective film adhered to at least one surface of the polarizing element has a ratio of two. As the resin having a lower water vapor permeability of acetyl cellulose, a polyester resin, a polycarbonate resin, an acrylic resin, an acrylic resin, or an amorphous polyolefin resin can be used. The type of the polyester resin used for the film is not limited to a specific substance, but the enthalpy is polymerized in terms of mechanical properties, solvent resistance, scrach resistance, and cost. Polyethylene terephthalate is more desirable. The so-called bismuth phthalate polyethylene means a structure of repeating unit (constitirti〇nal repeating unit) 80 mol per hundred (mole / 〇 or more is The resin composed of terephthalate may contain a constituent unit derived from another copolymerization component.

Further, in order to obtain an ideal glass transition temperature or to obtain a viscosity which is ideally mixed, it is desirable to use a chain-transfer agent for polymerization. The amount of the bond transfer agent can be appropriately determined depending on the type and composition of the monomer. In addition, acrylic acid (type) resin "press lysate", if necessary, may also contain conventional additives, such as the conventional additions - examples can be cited: lubricants (lubricant), anti- Antibl〇cking agent, thermal stabilizer, antioxidant, antistatic agent (antis1: a1: ic agent), light stabilizer (1 lght resistance agent), impact modifier (丨师此Seven modifiers, surfactants, etc. However, since it is a protective film laminated on a polarizing film, transparency is a necessary condition, and it is preferable to add these addition amounts to a minimum.

[0118] The amorphous poly olefin resin used as a ruthenium film is usually norb〇rnene or a derivative thereof, such as dimethylene octahydronaphthalene ( Dimethanooctahydronaphthalene) ' is a compound having a polymerized unit composed of a polycyclic cyclo-olefin; in the case of a double bond having a ring-opened polymer of 60 201231598, It is desirable to use it as a hydrogenation. The ruthenium-free polystyrene resin may be a cyclic olefin and a chain-like dilute hydrocarbon copolymer, or a polar group (p〇lar gr〇up) may be introduced.

When the amorphous polyolefin-based resin is formed into a film, a conventionally known method such as a solvent cast method or an extrusion molding method can be used for film formation. When the amorphous polycondensation hydrocarbon resin is used as a protective film, in order to obtain good adhesion, it is preferable to perform blooming treatment before applying the adhesive (four).

On the first surface of a piece of material, the rate of water vapor transmission rate is relatively high. ^ When the protective film is made by Qing, the relevant water vapor can pass through the surface of the grease film. Polyvinyl alcohol can also be used. The adhesive of the adhesive or the like = the external adhesive.

[0128] * Method for Producing Polarizing Plate The polarizing plate of the present invention is produced by a method of manufacturing a polarizing element of the prior art, a polycarbonate resin of a sage, a propylene resin, and an amorphous resin. a protective film made of a transparent resin film made of a resin, the adhesive surface of the two of which is coated with an adhesive for applying the photocurable adhesive previously described; and, the transfer of the crucible to the medium, The bonding operation of the polarizing element and the protective film 66 201231598; and, with the adhesive layer as a medium, the hardening operation of hardening the photohardenable agent between the polarizing element and the protective film is separated. The method can produce the polarizing plate of the present invention by including the above operations. [0129] The adhesive coating operation is applied to the adhesive coating operation, and the photo-curable adhesive is applied to at least the upper side of the polarizing element and the protective film. When the surface of the polarizing element or the protective film is directly coated with the photocurable adhesive, the coating method thereof is not particularly limited. For example, a doctor blade forming method can be used (d〇ctor blade method, bar coating) (wire bar c〇ater) 'Mold coating machine (such as (10) thin), angle wheel coater (6) surface (10), etc., gravure coating machine (gravure (10) W, etc. various granulation methods. Also, can also Between the polarizing element and the protective crucible, the photocurable adhesive previously described is spread, and then the drum is repeatedly applied to spread it evenly. The ambient temperature of the adhesive coating operation is more suitable. Ideally, it is 15~3〇°C, especially ideal for 2Q~ muscle. Also, the relative degree of coating work environment, 乂8 (U below, more ideally, on the next, then more The fineness is plus ~ orphan, especially ideal is 40~60%. [0 1 3 0] 67 201231598 * Adhesive work and then 'photocurable adhesive coating» 4 After the mi complex, provide the bonding operation. This bonding operation , ^ 'In the previous coating operation, the surface of the polarizing tree was coated with a photocurable adhesive p When the surface of the protective film is coated with a photocurable adhesive, the polarizing element is superposed on the adhesive, and the polarizing element and the spectrum are immersed in the adhesive. Between the guaranty, the light-curable adhesive flow cloth = correction, the new state, the polarizing element and the protective film overlap each other. The protective film of the polarizing element, both sides make the photocurable adhesive of the invention invention j, partial On both sides of the first reading, the photo-curable adhesive is used as the medium, and the protective film is weighted. Therefore, the 嶋τ, (4) the protective film on one side of the component; the polarizer side and the protective and polarized components on both sides In the case of _, the protective side of the two sides is tied with a fresh squeak. The material of the fading tube (10) can be made of metal or rubber, and the same material can be used for the same material f, or [0131] * Hardening work - As described above, the uncured photocurable adhesive is used as a finished product in a state where the medium is transferred and the protective film is adhered, and then hardened.

In the operation, the active energy is used to illuminate the graded adhesive to make the adhesive layer containing epoxidized person, (meta) acrylate and oxetane (QX hardened, #低水化0物荨) Partial k-piece and film _ in the case of the material element single-sided adhesion protection 68 201231598 film, the active energy line from the side of the polarizing element or the protective film side of the side of the irradiation is possible. When the protective film is adhered to both sides of the polarizing element, the active energy source is irradiated from the protective film on the side to the side, which is advantageous for simultaneous hardening of the photocurable dots on both sides. However, the UV coating is provided on the protective film on the side. In the case of the agent, for example, a cellulose resin film prepared with a UV absorber is used as a protective film, and when the active energy source is ultraviolet rays, usually, the other protective film is not irradiated with the ultraviolet absorber. [0132] As the active energy source', visible light, ultraviolet light, X-ray, electron beam, etc. can be used, but it is easy to obtain and the curing speed is sufficient. The light source of the active energy source is not particularly limited, but a low pressure mercury (vapor) lamp having a light emission distribution at a wavelength of 400 nanometers (nm) or a medium pressure mercury lamp ( Medium pressure mercury (vapor) lamp, high pressure mercury (vapor) lamp, ultrahigh pressure mercury (vapor) lamp, chemical lamp, black lamp "UV lamp" (black) -light lamp), microwave excitation mercury (vapor) lamp, metal halide lamp, Light-Emitting Diode lamp, etc. can be used. 69 201231598 [0133] The light irradiation intensity of the photocurable adhesive is determined according to each target composition, and is not particularly limited, but the irradiation intensity of the effective wavelength range of the activated polymerization initiator, such as UV-B "280~ The 320 nm (nm) medium wavelength range of UV rays, with 1 to 3,000 mW/cm 2 (111?/(:1112) is more desirable. 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, the radiant heat from the bulb and the heat of the photocurable adhesive are polymerized. The yellowing of the photocurable adhesive (turn yell QW) and the deterioration of the polarizing element may occur. [0134] There is no particular limitation on the photohardening recording time of the lying light irradiation, and the hardening composition of the miscellaneous county is controlled, but the integrated light amount of the product of the irradiation intensity and the irradiation time (Integra1: ed irradiati〇n) ) is set to Cong-b, at ==5'000 mJ/sq _« (:1112) is ideal. If the total amount of light is less than 10 joules per square centimeter, the active species from the polymerization initiator will be insufficiently produced, which may cause hardening of the adhesive layer =: on the other hand, the accumulated light amount exceeds 5, Joule, flat '(four) time becomes very long, which is unfavorable for improving productivity [0135] After irradiating the active energy line to vaporize the photocurable adhesive, the degree of polarization of the polarizing element 70 201231598 (degree of degreeati〇) n), transmittance (following surface) and hue (color phase; hue), as well as the transparency of the protective film, etc., it is more suitable for curing without reducing the thickness of the polarizer. . [0136] The polarizing plate thus obtained has a thickness of an adhesive layer of usually 5 μm.

Below Um), it is more desirable to be 2 μm or less, and more desirably less than 10 μm. [0 13 7] * Optical member When a polarizing plate is used, an optical member in which an optical layer exhibiting an optical function other than the polarizing function is laminated on one side of the polarizing plate may be formed. An optical layer laminated on a polarizing plate for the purpose of forming an optical member, such as a reflective layer, a semi-transmissive reflective layer, a light diffusing layer, a phase difference plate, and a condensing fiim A brightness enhancement film or the like is used to form various members such as a liquid crystal display device. The reflective layer, the semi-transmissive reflective layer, and the light-diffusing layer are members used in a case where a polarizing plate of a non-reflective semi-transmissive type or a diffusing type is used as an optical member. In the liquid crystal display device of the display type in which the light incident on the viewing side is reflected, the liquid crystal display device can be easily thinned by omitting a light source such as a backlight. Further, the semi-transmissive polarizing plate is applied to a reflective type display in an alum, and a liquid crystal display device of a type which is displayed in a dark place using a light source such as a backlight. As the optical member of the projection type polarizing plate, for example, a foil made of a metal such as aluminum or a vapor deposition film may be attached to the protective film on the polarizing element to form a reflective layer. As the optical member of the semi-transmissive polarizing plate, for example, the reflective layer may be formed as a semi-anti-hybrid layer (_heart), or a reflective film containing a pearl pigment and a translucent layer may be attached to the polarizing plate. m is used as an optical member of a diffusing type polarizing plate, for example, a method of applying a matte film on a polarizing plate, a method of applying a microparticle-containing resin, a method of adhering a film containing a microparticle, and the like, using various methods A structure in which fine concavities and convexities are formed on the surface. [0139] The formation of an optical member of a polarizing plate for remote reflection and diffusion is formed by, for example, reflecting on a fine uneven structure surface of a diffusing type polarizing plate (4) A method such as a reflective layer of a concavo-convex structure can be used to create such a kind of eccentricity. The reflective layer of the fine concavo-convex structure diffuses human light by diffusion (10) Qiu Can (8), and has the ability to prevent directivity and glare. (glare), suppressing the imbalance between light and dark (Essence of the lion). In addition, the resin and film containing microparticles diffuse the incident light and its reflected light through the ageing layer. The reflective layer having a fine uneven structure on the reflective surface can be vapor-deposited by, for example, vacuum deposition, ion plating, sputtering, or the like. Or a method such as plating, which can be directly attached to the surface of the fine concavo-convex structure, and can be used for the preparation of fine particles of the surface fine concavo-convex structure, for example, an average particle diameter of 〇.
