Description

201223758 VI. Description of the Invention: [Technical Field of the Invention] The present invention relates to a liquid crystal display (LCD, Liquid)

Optical film having an antistatic layer in front of a display (video display device) such as a cathode display device (CRT) or a cathode display panel (PDP, Plasma Display Panel) and the antistatic layer The composition 'and the polarizing plate and the display panel using the optical film. [Prior Art] In the above display, an optical film including a layer having various functions such as antireflection, hard coat or antistatic property is usually provided on the outermost surface. In addition, in the present specification, hard coating is sometimes referred to simply as "HC". As one of the functional layers of such an optical film, an antistatic layer for imparting antistatic properties is known. The antistatic layer is made of a metal oxide-based conductive ultrafine particle, such as tin oxide (tick, 7 TW) or oxidized with tin _0, hand · Tin 0xide. Conductive composition of money shouting (four) is an antistatic agent such as conductive materials: into (for example, patent silk). In order to make the required antistatic property and optical impurities (low fog value or high, 'coexistence, by forming a first line transmittance of antimony containing antistatic agent) to give the desired Features. ·~ (4) The film layer of about (4) is displayed in the above-mentioned X Ί, 丝 贝 不 与 与 与 与 与 与 与 , , , , , , , 硬度 硬度 硬度 硬度 硬度 硬度 硬度 硬度 硬度 硬度 硬度 硬度 硬度 # # # # # # # # # 100124540 4 201223758 The following is an optical film structure in which an antistatic layer of a film is provided on a cellulose triacetate (hereinafter sometimes referred to as a "TAC (Triacetyl Cellulose)" substrate, and is disposed on the antistatic layer. However, the antistatic layer-based film has the following problems: pentaerythritol triacrylate (hereinafter, sometimes referred to as "PETA (Pentaerythritol triacrylate)" or dipentaerythritol hexaacrylate (hereinafter referred to as "PETA (Pentaerythritol triacrylate)" In some cases, the amount of the binder component and the antistatic agent, which are simply referred to as "DPHA (Di-Pentaerythritol hexaacrylate)", is limited, and the adhesion to the HC layer adjacent to the antistatic layer is likely to be insufficient. The material/antistatic layer/HC layer is an optical film having a basic structure, and the interface between the antistatic layer and the HC layer and the interface between the antistatic layer and the substrate are intimate at each interface. The interface between the antistatic layer and the HC layer is crosslinked and bonded to each other by the reactive groups of the antistatic layer and the HC layer, but at the same time, the antistatic layer is required to exhibit antistatic properties. In the case of metal oxides, in order to resist the antistatic property of the 'electric layer,' the microparticles of the antistatic agent must be in close contact with each other, so a large amount of antistatic agent is added, but there is an increase in the haze value or the transmission of the whole light. 'If the optical properties are emphasized and the metal oxide is reduced, the antistatic performance is difficult to exert. Further, if the amount of the antistatic agent is increased, the amount of the binder component at the interface between the antistatic layer and the adjacent layer is insufficient.

The possibility that the adhesion between the electrostatic layer and the adjacent layer is deteriorated. However, if the importance of adhesion is reduced and the main oxide of M is reduced, antistatic performance is difficult to exert. 100124540 5 201223758 In the case where the antistatic agent is a quaternary ammonium salt, antistatic properties are exerted for the antistatic layer. There must be more quaternary ammonium salts in the layer than the binder. Alternatively, the quaternary ammonium salt must be concentrated in the vicinity of the interface of the antistatic layer adjacent to the HC layer. However, in such a case, there is a possibility that the quaternary ammonium salt present in the vicinity of the interface hinders the adhesion between the antistatic layer and the HC layer, and the binder component at the interface between the antistatic layer and the adjacent HC layer (having The amount of the component which increases the reactivity of the crosslinking layer with the HC layer is insufficient, and the adhesion between the antistatic layer and the adjacent HC layer is deteriorated. However, if the importance of adhesion is reduced and the amount of salt recorded at the fourth level is reduced, the antistatic property is deteriorated. In order to coexist the antistatic property and the adhesion, a method of simply increasing the amount of the binder component such as PETA (pentaerythritol triacrylate) or DPHA (dipentaerythritol hexaacrylate) may be considered, but if such a binder component is added The amount of the antistatic layer is increased, and the curl of the antistatic layer ((4)) becomes large, and the amount of the antistatic agent dispersed in the antistatic layer is also increased. 'There is a problem of increased costs. Further, in order to improve the adhesion, a method of increasing the composition of the adhesive towel having an anti-ship base may be considered. However, as described above, the amount of the antistatic agent necessary to exhibit antistatic properties is limited. It is therefore difficult to adopt this method. Further, as described above, since the total amount of the binder component and the antistatic core contained in the layer of the antistatic layer as the film is limited, if the amount of the epoxy resin is to be reduced, the amount of the binder component is increased accordingly. Increasing the adhesion of the antistatic layer | HC layer, there is a problem that the antistatic agent <_(10) is small, resulting in a decrease in electrical performance of antistatic 100124540 6 201223758. On the other hand, at the interface between the antistatic layer and the substrate, in order to adhere the antistatic layer to the substrate, it is necessary to infiltrate the binder component of the composition of the antistatic layer into the substrate, and in the substrate and At the interface of the antistatic layer, the binder component that penetrates into the substrate hardens and bonds with the binder component that forms the antistatic layer. In the case where the antistatic agent is a quaternary ammonium salt, it is known to use a quaternary ammonium salt having a relatively large molecular weight in order to improve durability or antistatic property. However, if the molecular weight of the quaternary ammonium salt is large, the binder component of the composition of the antistatic layer is difficult to penetrate into the substrate, and therefore, in order to obtain the adhesion between the antistatic layer and the substrate, it is necessary to use a large amount of the permeable solvent. Or use a binder of a lower molecular weight that can penetrate into the substrate. However, in this case, there is a problem that the adhesion between the interface of the antistatic layer and the HC layer is deteriorated. Further, it has been known that a barrier resin can be prevented by using a permeable solvent, and the appearance can be improved. However, when a permeable solvent is used, a new interface may be formed in the substrate. In addition to the above-described deterioration in adhesion, there is also a problem that interference fringes are generated and the appearance is deteriorated. [Prior Art Document] [Patent Document 1] Japanese Patent Laid-Open Publication No. 2009-086660 (Summary of the Invention) The present invention has been made to solve the above problems, and the first OBJECTIVE OF THE INVENTION The present invention provides a curable resin composition for an antistatic layer which is excellent in optical properties and appearance, has excellent antistatic properties, and is adjacent to the HC layer and the TAC group. An antistatic layer excellent in the adhesion of the material. Further, a second object of the present invention is to provide an optical film which has an antistatic layer formed using the above composition and which is excellent in dust adhesion prevention property. Further, a third object of the present invention is to provide a polarizing plate which has the above optical film. Further, a fourth object of the present invention is to provide a display panel 'which has the above optical film. (Means for Solving the Problem) The inventors of the present invention conducted an effort to study, and as a result, have found that 'the binder component contained in the composition of the antistatic layer is used for the crosslinking density of the surface and the adjacent HC layer. And obtaining a binder component having a relatively small molecular weight of 900 or less, such as PETA or DPHA, which can be substantially infiltrated into the TAC substrate, or from the interface of the TAC substrate and the HC layer according to the binder component. The surface penetrates to the depth of the back side of the TAC substrate without the HC layer, and as a result, the binder component is biased in the substrate, and the binder component contained in the antistatic layer on the substrate is reduced, and the HC layer and the anti- The interface at the interface of the electrostatic layer is insufficient in the reaction. Therefore, the adhesion between the antistatic layer and the HC layer may not be sufficiently obtained. Further, it is also known that if the portion penetrated into the inside of the TAC substrate does not penetrate in a gradient form, the infiltrated material is all the same. 100124540 8 201223758 The ground penetrates to the depth of the (4) of the TAC base (4), and a point is formed in the substrate. A new interface is created in the substrate through the layer, and interference fringes and the like are generated to cause deterioration in appearance. Therefore, the inventors of the present invention found that the anti-static _ _, the genus is transfused to the TAC or the Wit to the TAC substrate by the (4) shot.

'• The specific molecular weight of the mixture component of the amino acid uric acid acetate, and the adhesion of the Longzhou functional monomer penetrated to the TAC substrate) is set to the mosquito level, which can form sufficient antistatic properties, and with the HC layer and The k-electrostatic layer of the tac substrate excellent in adhesion can be obtained as an optical unit, and excellent dust adhesion prevention performance can be obtained, thereby completing the present invention.

When the HC layer is laminated to form an optical film, sufficient dust adhesion prevention property is also ensured. First, the film thickness of the antistatic layer is set by a film of about 〜1 due to optical properties and transparency, but in the case of such a film layer, in order to impart antistatic properties, it is necessary to make most of the composition in the layer. Since it is an antistatic material, it is not possible to add a sufficient amount of some adhesive agent having a reactive group necessary for exhibiting adhesion to a substrate or a layer above it. Therefore, in the present invention, the film thickness is increased to a certain extent, and the adhesion between the antistatic layer and the adjacent layer is ensured, so that the addition of the binder component having a reactive group other than the antistatic material can be sufficiently changed. It is possible. Further, by setting the ratio of the amino phthalic acid acrylate (c) to the total amount of the polyfunctional monomer (B) and the amino phthalic acid acrylate (C) to the above range, even on the TAC substrate The antistatic layer and the hc sheet are sequentially formed on the side of the taC substrate, and also because the acrylamide-based (C) does not penetrate into the TA c substrate or the difunctional monomer (8) does not (4) penetrate into the TAC substrate. By the acrylamide (C), sufficient adhesion between the antistatic layer and the HC layer can be obtained, and since the polyfunctional monomer (B) penetrates into the TAC substrate, an anti-electrostatic layer can also be obtained.

Further, regarding the definition of the film and the moon material, in the definition of JIS_K69, the sheet means a flat product which is thin and has a thickness smaller than the length and the width, and the film means that the thickness is extremely small compared with the length and the width, and The flattened article having the thinnest A thickness is arbitrarily limited, which is usually supplied in the form of a roll (four). Therefore, the thickness of the sheet is particularly thin, which may be referred to as a film. However, since the boundary between the sheet and the film is not clear, it is difficult to distinguish clearly. Therefore, in the present invention, both the thicker and the thinner are included. The meaning is defined as "film". In the present invention, the resin includes a polymer in addition to a monomer or an oligomer, and means a component which becomes a matrix of an antistatic layer or another functional layer such as an Hc layer after curing.

In the present invention, the term "permeation" means that the TAC substrate is dissolved or swollen. In the present invention, the solid portion means a component from which a solvent is removed. (The curable resin composition for an antistatic layer) The curable resin composition for an antistatic layer of the present invention is characterized by comprising: (A) an antistatic agent, and (B) having two or more photocuring properties in one molecule. a polyfunctional monomer having a molecular weight of 900 or less, and (C) an amino amide having a weight average molecular weight of 1,000 to 11,000 and having a weight average molecular weight of 1,000 to 11,000 The ratio of the (A) to the total amount of the (A), (B), and (C) is 1 to 3 % by mass, and the total amount of the (C) relative to the (B) and (C) The ratio is 1 to 4% by mass. By setting the ratio of the antistatic agent (A) to the above range, the antistatic layer can impart antistatic property and also ensure sufficient dust adhesion when the HC layer is formed on the antistatic layer having a film thickness. Preventiveness, by setting the ratio of the urethane urethane (C) to the total amount of the polyfunctional monomer (b) and the urethane acrylate (C) as the above-mentioned TBI substrate Antistatic is formed sequentially from the side of the TAC substrate: 2, 100124540 15 201223758, due to the infiltration of the crucible into the TAC substrate, or the penetration of the TAC to the TAC compared to the polyfunctional monomer (9).

The following "antistatic agent (A), polyfunctional monomer (B), and acrylamide as the essential components of the composition for an antistatic layer of the present invention. The phthalic acid ester (C) and other components which are appropriately contained as needed are described.

It is preferable that the antistatic agent (A) is a quaternary ammonium salt having a weight average molecular weight of from 1 Å to 50,000 when it penetrates into the TAC substrate and is excellent in coatability. The coating property is deteriorated, and if it is less than the above lower limit, the antistatic agent easily bleeds out to the interface between the antistatic layer and the HC layer, and the adhesion between the antistatic layer and the HC layer may be deteriorated. In the past, the film thickness of the antistatic layer was set by a film of about 1 to 1 //m due to optical properties and transparency, but in the case of such a film layer, it is necessary to impart an antistatic property. Most of the materials are made of an antistatic material, and a resin composition having a sufficient amount of a reactive group necessary for exhibiting adhesion to a substrate or a layer above it is mixed. Therefore, in the present invention, the thickness of the word film is 1 to 5 μm, which is thicker than before, and ensures the adhesion between the antistatic layer and the adjacent layer, so that the antistatic material can be sufficiently made to have an anti-static material. The resin constituting the physics of the county, the loss of the text paid this. Due to the increase in thickness, the antistatic agent of the mouth is selected to have a higher transparency. In the case of the side 100124540 17 201223758, the surface is preferably an organic material having higher transparency than the inorganic material, and further, the quaternary ammonium salt having a very small coloration among the organic materials is most suitable.

Moreover, the polyfunctional monomer penetrates into the TAC substrate and hardens by at least a portion thereof, and also contributes to the improvement of the antistatic layer and the TAC substrate. When the molecular weight of the polyfunctional monomer (B) exceeds 900, the permeability to the TAC substrate is lowered, and there is a possibility that sufficient adhesion between the antistatic layer and the TAC substrate is not obtained. The molecular weight of (B) may be 900 or less, but the polyfunctional monomer (B) is appropriately infiltrated into the TAC substrate, and the adhesion between the antistatic layer and the HC layer and the antistatic property (surface resistance value) are obtained. From the viewpoint of high coexistence, the molecular weight of the polyfunctional monomer (B) is preferably 230 or more, more preferably 29 〇 100124540 19 201223758 or more.

The photocurable group of the polyfunctional monomer (B) is two or more in order to form a crosslinked structure. It is preferable to have three or more, and more preferably five or more. If it is three or more ', it is easy to obtain sufficient entanglement of the antistatic layer with the η c layer and the Ta c substrate. The same as the photocurable group exemplified in the antistatic agent. Examples of the polyfunctional monomer (B)' include pentaerythritol tri(meth)acrylate, dipentaerythritol hexa(indenyl)propionate, and Pentaerythritol penta(indenyl) acrylate, trihydroxyf-propane tris(mercapto) acrylate, and trishydroxypropyl propane hexa(meth) acrylate and such modified bodies.

If not quality. /. The adhesion between the antistatic layer and the Hc layer and the tantalum substrate could not be obtained. When the amount is more than 99% by mass, the ratio of the amic acid amide is less. The sufficient adhesion between the antistatic layer and the HC ’ ' is not obtained. (C: Amino phthalic acid acrylate) Amino acid carboxylic acid vinegar (C) is a binder component which becomes a matrix of an antistatic layer after hardening, and has 6 or more (meth)acrylic groups in the i molecule. Further, the weight average molecular weight is 1 GGG 〜1!_, preferably from 1 to 1 Å, more preferably from 1,000 to 5,000. By controlling the weight average molecular weight to be 1_~U_, the coating property is good, does not penetrate into the TAC substrate, or is more difficult to penetrate into the TAC substrate than the polyfunctional monomer (B), and it is easy to control the permeation, and surely Present in the entire antistatic layer. When the antistatic agent (A) is a quaternary ammonium salt, the compatibility with the hydrophilic compound is preferred as the nature of the compound. Therefore, if the binder in the antistatic layer is a compound having an OH group (PETA, pentaerythritol tetraacrylate, DPPA (dipentaerythritol pentaacrylate), etc.), the antistatic agent is excessively dispersed throughout the layer' Antistatic properties are not available. DPHA is known to be structurally free of sulfhydryl groups but is generally difficult to form on the synthesis. 6 100124540 21 201223758 is a functional group, and thus is actually a mixed compound with a 5- or 4-functional moiety, as it is usually commercially available. The compound of the 〇H group remains, so that the antistatic property is better. The dispersible person can be controlled _ in the hydrophobic resin of propyl-amino formate vinegar (Q. 纽 丙 胺 胺 胺 _ 旨 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 静电 静电 静电 静电 静电 静电 静电 静电 静电 静电 静电 静电 静电 静电 静电 静电It is true that (4) antistatic is excessively dispersed in the layer or oozes in the direction of the interface with HC. The reason why it is easy to ooze out in the direction of the HC interface is that, as described above, since the quaternary salt is like hydrophilicity, it is electrostatic. When the layer is layered, there is two gas on the surface, which reacts with the moisture in the air of 5 hai, and oozes out. And by having more than 6 (fluorenyl) acrylonitrile groups, it helps to improve the antistatic layer. The adhesion density of the reactive group in the Hc layer adjacent to or adjacent to the antistatic layer 'sends the adhesion between the antistatic layer and the sink layer. X, due to the penetration of the antistatic layer of the TAC substrate The reactive group of the functional monomer (8) and the cross-linking density of the (meth)acryloyl group or the polyfunctional monomer of the amino acid group (4) (6) present in the antistatic layer, and thus the amino acid group of the acrylic acid曱 (c) also helps to improve the adhesion between the antistatic layer and the TAC substrate. When you look at it, 'do not add acrylamide (C)' as long as it has a large amount of reactive groups in addition to antistatic ruthenium (B), but in order to control antistatic as described above. The variation of the agent (A) in the antistatic layer is difficult to control if it is only the polyfunctional monomer (8), and the propylene which is hydrophobic and has a large amount of reactive groups for the antistatic agent (A) is not dispersed 100124540 22 201223758 Acid amide phthalate (c). Also containing urethane acrylate (c) is also effective for suppressing the generation of curl (what is desired). If the weight average molecular weight of urethane amide (C) Less than 1〇〇〇, then

There is a possibility that the amino phthalic acid acrylate (c) easily penetrates into the TAC substrate and is excessively infiltrated into the TAC substrate, resulting in a decrease in the propylene sulfhydryl group at the interface between the antistatic layer and the HC layer, and it is difficult to obtain antistatic properties. The adhesion between the layer and the HC layer. If the weight average molecular weight of the urethane acrylate (C) exceeds iiooo, there is a possibility that the coatability is deteriorated. As long as the urethane urethane (the fluorene has 6 or more (fluorenyl) acrylonitrile groups, it may contain other crosslinking reactive functional groups such as ionizing radiation curable unsaturated groups. (Methyl) acrylonitrile group As long as it has a total of six or more propylene ketone groups and a methacryl oxime group, it may have only an acryloyl group or may have only a fluorenyl fluorenyl group. As the acrylamide phthalate (C) of the present invention, It is not particularly limited as long as it has an amino phthalic acid vinegar bond (-NH-C0-0-), has 6 or more (meth) acrylonitrile groups, and has the above weight average molecular weight. ((:), preferably a light-transmitting light which is transmitted through a coating film, and an ionizing radiation which is a resin which is hardened by ionizing radiation represented by ultraviolet rays or electron beams, may be appropriately used depending on required properties and the like. A curable urethane urethane, another known urethane phthalate, etc. 100124540 23 201223758 The commercially available product of the above-mentioned urethane phthalate is, for example, a Japanese synthetic chemical described in Patent Document 1. The trade name of the company (shares) is manufactured by UV1700B, the brand name of the company manufactured by Gensei Industrial Co., Ltd., and the brand name of the company is BS577, which is manufactured by Arakawa Chemical Industry Co., Ltd., and the new Nakamura Chemical Industry Co., Ltd.

The trade names are U15HA, U15H, U9HA, U9H, U6HA and U6H. In the antistatic layer composition of the present invention, the urethane acrylate (c) satisfies the content ratio of the above antistatic agent, and is relative to the above polyfunctional monomer (B) and urethane acrylate ( c) The total amount is % by mass. If it is less than 1% by mass, sufficient adhesion between the antistatic layer and the HC layer cannot be obtained. also,

If the proportion of the polyfunctional monomer (8) exceeds 40% by mass, the sufficient adhesion between the antistatic layer and the TAC substrate cannot be obtained. The ratio of the X-acrylic acid amide vinegar (c) is relative to the above total amount (b 1 to 4% by mass, but preferably 5 to 3% by mass. Thus, by the polyfunctional monomer in the binder (8) Acrylic acid carboxylic acid vinegar (Q ratio is appropriate, antistatic agent (4) will not be excessively dispersed in the antistatic layer 'and will not ooze out' can be concentrated in the layer to the extent that it can exert antistatic properties. It is this composition, and the surface of the antistatic layer can be turned into less than 1χ1〇12 Ω/□. ' ^ Antistatic layer composition, in addition to the above components (4), (8) and (C), A suitable solvent and a polymerization initiator are contained. Hereinafter, the other components are described by force σ. ', 100124540 24 201223758 (solvent) As a cardiac agent, a ketone-based solution such as acetone described in the patent document can be used. Acetic acid, such as a solvent, a nitrogen-containing solvent such as acetonitrile, methyl glycol, etc., a solvent, an ether solvent such as THF, a halogenated hydrocarbon solvent such as dichloromethane, and methyl sulfus The diol is a osmotic solvent such as a solvent. The permeating solvent is preferably selected from the group consisting of At least one of the group consisting of methyl acetate, ethyl acetate, butyl acetate, mercaptoethyl ketone, decyl isobutyl ketone (MIBK, MethylIs〇butyl Ketone) and cyclohexanone. Non-permeable solvents such as propylene glycol monomethyl ether (PGME, Pr〇pylene Glyc® Monomethyl Ether), n-propanol, isopropanol, n-butanol, second butanol, isobutanol and tert-butanol are used. The solvent may be used singly or in combination of two or more. In the composition for an antistatic layer of the present invention, it is presumed that the above polyfunctional monomer (B) can be promoted by using a permeable solvent. It is preferable to use a permeable solvent in order to infiltrate the TAC substrate and improve the adhesion between the antistatic layer and the TAC substrate. Further, in the composition for an antistatic layer of the present invention, it is presumed that non-permeability is used. The solvent can suppress the penetration of the urethane urethane ((:) toward the tac substrate and improve the adhesion between the antistatic layer and the HC layer, and it is preferred to use a non-permeable solvent. Therefore, in the present invention In the composition for antistatic layer, the solvent is a kind of 1001 24540 25 201223758 In the case of 'preferably using a seepage solvent, but in the case of two or more solvents, it is best to combine the materiality_ with the twisting and twisting. The reason is that even if it is a solvent (only infiltration) Solvents can also be controlled by the molecular weight of the amino acid (6), and the permeability of the solvent can be more compatible with the non-permeable solution. (4) _ One, shouting the stability of the antistatic layer using the composition When the osmotic solvent is used in combination with the non-permeable solvent, the mass ratio is preferably a permeable solvent: non-permeable solvent = 1 〇〇: 〇 〜 5 〇: 5 〇, preferably 90: U) to 5 (): 50, and is 30 to 500 parts by mass based on 100 parts by mass of the total solid content of the antistatic composition. (Polymerization Initiator) The polymerization initiator is a component which starts or promotes the crosslinking reaction of the above-mentioned binder component (B), and if necessary, a conventionally known radical and cationic polymerization initiator or the like can be appropriately selected and used. As the radical polymerization initiator, for example, Irgacurel 84 (l-hydroxy-cyclohexyl-phenyl-ketone) manufactured by Ciba Japan Co., Ltd. can be preferably used. In the case of using a polymerization initiator, the content thereof is preferably from 0.4 to 2.0% by mass based on the total mass of the total solid content of the composition for the antistatic layer. The antistatic layer can be obtained by setting the amount of the polymerization initiator used in the composition for an antistatic layer to 1/10 to 1/2 of the amount of the polymerization initiator used in the HC layer as described above. The reactive groups remain in large amounts. Thereby, the reaction is difficult to carry out, so that the occurrence of curling is also prevented. (Preparation of a curable resin composition for an antistatic layer) 100124540 26 201223758 The curable resin composition for an antistatic layer can be obtained by mixing and dispersing the above components (A), (b) and (C) in a solvent. . Further, even if the above (A), (B) or (C) component has sufficient fluidity without a solvent, it may be solvent free. A well-known method such as a paint shaker or a bead mill can be used for the mixed dispersion. In the curable resin composition for an antistatic layer of the present invention, the film thickness of the curable resin composition for an antistatic layer can be made 1 to 5/ by setting the antistatic agent (A) to the above range. The surface resistance of the cured product of zm is less than 1 x 10 Ω/□. By making the antistatic layer have such an antistatic property, even if the HC layer having a relatively thick film thickness is laminated, excellent dust adhesion prevention performance can be exhibited in the entire optical film. If the film thickness of the antistatic layer is less than 1 V m, it is necessary to increase the amount of the quaternary ammonium salt as the antistatic agent in order to maintain the same surface resistance. However, in this case, the reactive group of the antistatic agent is reduced. The possibility that the adhesion between the antistatic layer and the He layer deteriorates. When the film thickness of the antistatic layer exceeds 5/im, the surface resistance is likely to be expressed, but there is a possibility that curling occurs, the cost increases, and the handleability deteriorates. Further, 'in the composition for antistatic layer', the total amount of the antistatic agent (A) relative to the antistatic agent (A), the polyfunctional monomer (B), and the amino acrylate acrylate (c) is 5 〜20% by mass, and the total amount of the amino phthalic acid acrylate (c) relative to the polyfunctional monomer (B) and the urethane acrylate (c) is 5 to 3 〇 mass%' except that sufficient In addition to the antistatic property, the optical film can also be obtained. 100124540 27 201223758 The excellent durability of the wettability to ultraviolet rays (uv). (Optical film) The optical film of the present invention is formed on one side of a cellulose triacetate substrate, and an antistatic layer and a hard coat layer having a film thickness of 1 to 5 are provided adjacent to each other from the side of the cellulose triacetate substrate. The antistatic layer includes a cured product of a curable resin composition for an upper surface layer, and the polyfunctional monomer is permeable to a region on the interface side of the antistatic layer side of the triacetylcellulose substrate. hardening. ^ Even if the anti-static layer of the film thickness of 1 to 5 " m and the optical film of the Hc layer are provided on the surface side of the TAC substrate from the side of the TAC substrate, the antistatic layer is cured by the antistatic layer. The cured product of the resin composition can still have sufficient dust adhesion prevention property, and the adhesion between the Hc layer and the antistatic layer is excellent. Further, the polyfunctional monomer (8) is infiltrated into the boundary region of the antistatic layer side of the TAC substrate and hardened, and the adhesion between the antistatic layer and the tac substrate can also be obtained. As the entire optical film, excellent dust adhesion prevention performance can be obtained. In a preferred embodiment of the optical film of the present invention, the antistatic layer may be formed of a cured product of the antistatic layer composition, or the hard coat layer of the optical film, the antistatic layer, and the triacetate may be used. The grid connection between the cellulose substrates is 〇1〇〇1〇〇%, and is irradiated for 192 hours at a temperature of 40% per hour at a temperature of 5 〇〇w/m 2 After the ultraviolet rays (hereinafter referred to as "after UV (Uv) ultraviolet test ("), the 100124540 28 201223758 adhesion rate is 80 to 100%. The adhesion ratio indicates the adhesion between the HC layer, the antistatic layer, and the TAC substrate, that is, the adhesion between the antistatic layer and the HC layer, and the adhesion between the antistatic layer and the TAC substrate. It is conventionally known that the acryl-free phthalic acid ester (C)-containing only the polyfunctional monomer (B) as a binder, or even the amide-based phthalic acid ester (C) is not specified. In an optical film containing an antistatic agent (A), a polyfunctional monomer (B), and an amino phthalic acid acrylate (an antistatic layer composed of a cured product of a ruthenium composition), between the antistatic layer and the TAC substrate Although the adhesion is good, the adhesion between the antistatic layer and the HC layer is not sufficient. Thus, when the adhesion between the antistatic layer and the HC layer is insufficient, the adhesion test is performed, and the antistatic layer and the TAC group are used. Although there is no peeling between the materials, the antistatic layer and the HC layer are peeled off and peeled off. When the adhesion between the antistatic layer and the TAc substrate is insufficient, the antistatic layer and the TAC substrate are generated. Therefore, as an optical film, in order to obtain excellent adhesion, adhesion between the antistatic layer and the HC layer and adhesion between the antistatic layer and the TAC substrate are required. The composition for the antistatic layer is hardened. Forming an antistatic layer with a film thickness of 1 to 5 #m The adhesion between the antistatic layer and the Hc layer and the adhesion between the antistatic layer and the TAC substrate are excellent, and the optical film as a whole exhibits excellent adhesion. In particular, the adhesion is better than that of the optical film of the present invention. Excellent adhesion is also exhibited after the UV resistance test. 100124540 29 201223758 Fig. 1 is a schematic view showing an example of the layer constitution of the optical film of the present invention, which is one side of the side of the cellulose substrate 10, which is sequentially adjacent. The antistatic layer 20 and the hard coat layer are provided. Fig. 2 is a schematic view showing another example of the formation of the optical film of the present invention. The hard coat layer of the optical film similar to that of Fig. 1 is further provided with a low refractive index layer. 40. The following is a "triacetate cellulose substrate, an antistatic layer and a hard coat layer which are essential components of the optical (4), and a high refractive index layer, a t refractive index layer, and a low Other layers such as a refractive index layer, an anti-glare layer, and an anti-staining layer are described. (Diacetate cellulose substrate) The cellulose triacetate substrate used in the present invention is a cellulose triacetate film having high light transmittance. And as long as it is full (4) The physical properties of the optically thin translucent substrate can be appropriately determined, and the TAC substrate of the previously known hard-coated film or optical film can be appropriately selected. The TAC substrate in the visible light region of 380 to 780 nm The average light transmittance is preferably 80% or more, and particularly preferably 90% or more. Further, the light transmittance is measured by using an ultraviolet-visible spectrophotometer (for example, the product name UV-3100PC manufactured by Shimadzu Corporation). The TAC substrate may be subjected to a saponification treatment or a surface treatment such as an undercoat layer. Further, an additive such as an antistatic agent may be added. The thickness of the TAC substrate is not particularly limited 'usually 3〇~2〇〇 claws, preferably 40~200 // m. 30 100124540 201223758 (antistatic layer) The antistatic layer of the present invention is made of the above-mentioned antistatic layer hardening resin and is ordered It consists of hardened matter, and the glandular '' drink is 1~5/zm. If the film thickness is less than 1, a sufficient anti-static property is not obtained, and it is not possible to sufficiently add an adhesive which is necessary to ensure the adhesion of the other layers. If it is thicker than 5 // m, the antistatic agent does not exhibit a certain degree of tightness in the layer and the performance of the antistatic layer becomes large. Therefore, the workability is deteriorated, and if the film thickness is advanced, the film thickness is increased. "Thickness" increases the amount of antistatic agent contained in the 'thickness'. As the performance of the antistatic layer, the surface resistance is preferably less than 1 χΐ〇ΐ 2 β / □, more preferably Ιχίο11 Ω / □ or less, and further 1 χ 1 〇 ιο Ω / □ or less. As long as the surface f resistance I of the antistatic layer is good, the dust adhesion prevention property of the optical film in which the HC layer is laminated can be more excellent. (hard coat layer) The hard coat layer is a layer having a hardness of "H" or more in a pencil hardness test (4.9 N load) prescribed in JIS K5600-5-4 (1999), and imparts hardness to the optical film of the present invention. . The HC layer contains a cured product of a composition for a hard coat layer, and a previously known hard coat layer may be used, or may be a hardened material containing a composition for a hard coat layer containing only a binder component, or may be a composition. The polymerization initiator and the like listed in the composition for an antistatic layer are contained therein. In order to increase the hardness and the like of the HC layer, it is also possible to contain a previously known hardness-imparting component, for example, a reactive oxidizing agent having a crosslinking reaction with a binder component as described in JP-A-2008-165040.矽Microparticles. As a specific example, a resin composition containing an ionizing radiation curable resin as a transparent resin can be applied onto a transparent substrate, and the monomers, oligomers, and prepolymers contained in the resin composition can be mixed.

Moreover, the optical characteristics and appearance are also good. However, 'the tt is more than 2 cases, * does not contain polyfunctional monomer (8) or _ acid amine formic acid in the antistatic layer test, so the adhesion rate before the Lai uv test is good, but the UV resistance test The subsequent bonding rate is poor. In Comparative Example 3, since the polyfunctional monomer (8) was monofunctional, sufficient adhesion was not obtained. In Comparative Example 4, the molecular weight of the polyfunctional monomer (B) exceeded 1 Å, and the adhesion rate was low, and the adhesion rate after the UV resistance test was low. The reason for this is considered to be that the penetration of the polyfunctional monomer (B) into the TAC substrate is insufficient, and the adhesion between the TAC substrate and the antistatic layer is insufficient. In Comparative Example 5, the number of functional groups of the urethane acrylate (C) was 2 and less, and the adhesion rate was low, and the adhesion ratio after the UV test was particularly low. The reason for this is considered to be that the crosslinking caused by the acrylic acid decanoate (C) is small, and the adhesion between the antistatic layer and the HC layer is insufficient. In Comparative Example 6, the molecular weight of the urethane acrylate (C) was less than 1,000, and in particular, the adhesion after the UV resistance test was low. The reason for this is considered to be that the adhesion between the antistatic layer and the HC layer is insufficient due to excessive penetration of the acrylamide phthalate (C) into the TAC substrate. In Comparative Example 7, 'acrylic acid amide phthalate (Q molecular weight exceeds 10000, 100124540 52 201223758 and the adhesion rate is secret, especially after the uv recording is low, the surface resistance is also high, which can be considered as: C (4) (C) did not completely penetrate into the TAC substrate, and the relative amount of the antistatic agent (A) in the antistatic layer became less. In Comparative Example 8, the antistatic agent (A) contained less The surface resistance value was higher than that of Comparative Example 9, the antistatic agent (A) was contained in a large proportion, and the antistatic property was good, but the polyfunctional monomer (8) and the urethane carboxylic acid vinegar (C) which are binders were used. Therefore, the amount of adhesion is low. Therefore, in the comparative example 1G, 'the content of the polyfunctional monomer (8) is large, and the content of the amino acid group A (C) is small. The rate is low, especially after the UV test. The ratio of the polyfunctional monomer (B) is higher than that of the ruthenium case 11 because of the high proportion of the amide phthalate (C). Less, so the adhesion rate before the uv test is good, but the resistance is low after the test. The adhesion rate is low and the surface resistance value is high. It can be considered that the original j is only the solvent in the k electrostatic layer test is set to be permeable to the I electric layer: the acrylic acid carboxylic acid vinegar (6) is not sufficiently penetrated into the STAC substrate. The relative amount of the antistatic agent (A) against the moon and the cockroach is small. In the citric acid 12, the tetragonal salt is excessively dispersed and the surface resistance value is high because the amide acid group which is hydrophobic is not used. Also, it is not more _$ preventive. u J 2, a metal microparticle as an antistatic syrup is set to 100124540 53 201223758 to obtain the same amount of water as the fourth-order salt in the case of the total light transmittance ( In the case of the reference example 3, in order to obtain the necessary antistatic property regardless of the total light transmittance, more metal fine particles as an antistatic agent than the reference example 2 are blended, and thus the adhesion is made. It is inferior in nature. It is colored by the addition amount, and the total light transmittance is lower than that of the quaternary ammonium salt (88%), and the haze value (〇·8%) becomes high. For the examples, comparative examples, and reference examples Evaluation of dust adhesion prevention of optical film As a result, it is good when the surface resistance value of the laminate is less than lx1 〇 i2 Ω/□, but in other cases, the ash is largely attached. That is, if it is an antistatic layer having a preferable surface resistance value. In addition, even if an Hc layer is laminated thereon, it is possible to impart dust adhesion prevention property to the optical film.
