200920811 IX. Description of the Invention: [Technical Field of the Invention] The present invention relates to a resin film in which an adhesive layer is formed. In the present invention, the resin film to be used is, for example, an optical film containing a polarizing film or a retardation film, or bonded to the surface opposite to the adhesive layer of the optical film until use. Both sides of the surface protect the protective film. The present invention also relates to an optical layered body for liquid crystal display using a resin film on which the adhesive layer is formed. f * [Prior Art] The polarizing film is widely used by being mounted on a liquid crystal display device, and has a transparent protective film on two areas of a polarizer, and an adhesive layer is formed on at least one of the protective films. The _ film is placed on the adhesive layer to circulate. In addition, a polarizing film may be formed on both sides of the polarizer with a protective film, and a polarizing film may be formed on the retardation film side. Release the film. In addition, there are also cases in which the surface difference is in the order of (4) adhesive layer/clear film. The release film is peeled off from the polarizing boat, the ellipsic polarizing film, the retardation film or the like before being bonded to the liquid crystal cell, and is bonded to the liquid crystal cell via the exposed adhesive layer. Such a polarizing film, a circularly polarizing film, or a retardation film is caused by the generation of static electricity when the peeling film is peeled off and the sheet is affixed, and the prevention of this phenomenon is expected to be developed as one of the countermeasures. In Japanese Patent No. 3012860, a polarizing film in which a protective film is laminated on the surface of the polarizer film and an adhesive layer is provided on the surface of the protective film is used as an adhesive, and the use of 320560 6 200920811 ' A composition of an electrolyte salt and an organopolyoxane-propionic acid copolymer.

Layer side:: In the optical film with adhesive, although the adhesive is heated and cooled as the size of the optical film changes, the optical film and the adhesive layer can be combined, or the adhesive layer and the liquid crystal cell There is a phenomenon in which the glass can be lifted or peeled off. Therefore, it is also required that such a phenomenon does not occur, and the durability is required to be excellent. Furthermore, the distribution of the residual stress acting on the optical film exposed to high-strength is becoming uneven, and stress concentration is caused in the outer periphery of the film in the light 320560 7 200920811, and as a result, the outer peripheral portion is formed in the black display; Ai Bai produces the phenomenon of "white spotted lack of color", which may cause color unevenness - and therefore requires suppression of such "white spotted lack of color" or "colorless technology. In addition, it will be attached When the optical film of the adhesive is attached to the liquid crystal cell, when there is an incompleteness, although the optical film is first removed, the film is again re-boiled, but the adhesive is laminated when the peeling is performed. With the optical film being separated by the sword, it is required that there will be no residue on the unit glass, and there will be no phenomenon such as smashing, that is, the so-called rework is also required. The surface protection film is generally It is attached to the optical film which is formed on the one side of the film, and is attached to the optical film or the like which is the protected body, and is damaged or contaminated by the processing or the conveyance. For example, it is suitable for the partial or retardation film. The optical film 'is used to prevent damage 4 as the purpose' The above-mentioned adhesive layer for bonding to the liquid crystal cell is on the opposite side of the surface to be attached to the 兮": ==; although the optical medium is attached to the liquid crystal cell, it will be ordered by the #^ When 'electrostatic electricity will occur, if the alignment or liquid production of the electrostatic crystal molecules is earlier, there may be damage to the liquid film and Μ ί defects, placed on the surface of the film Household '% of various antistatic treatment.

When the side is attached to the glass substrate, in order to improve the adhesion between the adhesive layer and the glass substrate on the adhesive for forming the adhesive layer, it is preferable to contain the compounding compound, especially in the blending It is more preferable to contain a decane-based compound in the acrylic resin before the crosslinking. Examples of the hetero compound are, for example, vinyl trimethoxy hydride, acetamethylene diethoxy sylvestre, and vinyl ginseng (2').

The amount of the decane-based compound to be added to the adhesive is 100 parts by weight based on the non-volatile content of the acrylic resin (A) (the total weight when two or more types are used), and is usually 26 320560 200920811 0.01 to 10 It is preferably used in a ratio of about 0.05 to 5 parts by weight, based on the parts by weight. When the amount of the non-volatile enthalpy of the acrylic resin is 0.01 part by weight or more, the adhesion between the adhesive layer and the glass substrate is improved, which is preferable. Further, when the amount is 10 parts by weight or less, the decane-based compound tends to be prevented from flowing out of the adhesive layer, which is preferable. In the above-described adhesive, a cross-linking catalyst, a weathering stabilizer, a tackifier, a plasticizer, a softener, a dye, a pigment, an inorganic filler, a resin other than the acrylic resin (A), or the like may be further blended. Further, an ultraviolet curable compound is blended in the adhesive, and after the adhesive layer is formed, the ultraviolet ray is irradiated and cured to form a hard adhesive layer. Wherein, if the crosslinking agent and the crosslinking catalyst are simultaneously formulated in the adhesive, the adhesive layer can be prepared by the aging of the adhesive in a short period of time, and the resin attached to the adhesive can be inhibited in the resin film and adhered. The phenomenon of floating or peeling occurring between the agent layers, the foaming generated in the "agent layer", and the reworkability are also more favorable. As the cross-linking catalyst, for example, hexamethylene diamine B: amine, polyethylenimine, hexamethylenetetramine, di-ethyltriamine, dimethylamine: Preferably, the ketone diamine, the trimethylene diamine, and the polyamine-based tree cross-linking catalyst are compounded. ^ Liancai uses an isocyanate-based compound as an adhesive to form an adhesive composition, and forms an adhesive layer in a state where it is widely dissolved in a solvent. The substrate is coated on the substrate and dried to become 320560 27 200920811. The resin film of the adhesive of the present invention is produced in the production of β$ 〇. The viscous agent layer is in such a manner that the gel fraction is in the range of 50 to 99% by weight. The gel fraction is a value measured by the following (I) to (IV). And, the adhesive layer of about 8 (four) about 8 cm is bonded to the metal mesh (the weight of which is made diligent) by the SU of the center (10). = Weighing the above (1): the weight of the resulting composition, the weight of which is taken as I-man, folding the field in a manner to surround the adhesive layer - and the 4-person is stapled (Stapler) After living, weigh it and its weight is taken as Wb. =) Place the above (11) in a glass container to nail the mesh of the "i^:: force: into 60 W of ethyl acetate and impregnate it, and store it at room temperature for 3 days. ^ (IV) From The glass container was taken out of the glass container, dried for 12 hours, and weighed. The weight was taken as Wa, and the gel fraction was calculated according to the following formula: 'The amount of gel robes%MiWa_(Wb_Ws)_Wm}/(Ws_Wm )] When the gel fraction of the adhesive layer is 5 Gg or more, the durability tends to increase due to the adhesive layer, so it is better, and the gel fraction is less than or equal to the weight%. It is easy to manufacture, so it is better. The gel fraction of the adhesive layer is adjusted to 5 〇 to 99 wt.%, although it depends on the effective 9-point acrylic resin of the adhesive layer. However, if the amount of cross-linking agent is increased, the gel fraction will be changed to two. Therefore, it is preferable to adjust the gel fraction according to the amount of the cross-linking agent. Specifically, θ is the layer of the adhesive. The non-volatile content of the acrylic resin is 1 part by weight (the total amount is 2 or more), and the amount of the crosslinking agent is in the range of about 0.1 to 1 part by weight. With acrylic type 320560 28 200920811. Resin type t can be selected as appropriate. The gel fraction of the adhesive layer is on the "6 cc / 〇乂 (better than 75 reset 〇 / 较佳) and at 95 The resin film with an adhesive according to the present invention is provided with an adhesive layer formed of the above adhesive composition on at least one surface of the resin film.

Among them, a polymer film obtained by stretching a single axis or biaxially stretching a polycarbonate film or a cyclic polyolefin film is preferred. The one-axis retardation film is also called a wide viewing angle retardation film, a low photoelasticity retardation film, etc., but can be suitably used for any of them. In addition, optical anisotropy is exhibited by coating and alignment of a liquid crystal compound! The film of the raw film or the film exhibiting optical anisotropy by coating with an inorganic layered compound can be used as a retardation film. In the case of such a retardation film, there is also a film called a temperature-compensated retardation film, and a film obtained by twist-aligning a rod-shaped liquid crystal, which is sold under the trade name "LC film" by Nippon Oil Co., Ltd.

The protective film is preferably an acetaminophen-based resin film such as a plain film. In the above optical film, the linear polarizing film is a single-sided polarizing film (for example, a polyvinyl alcohol-based resin is formed into a κ8 or a double-sidedly coated Mogubit # / Wuxian film) Or the surface is covered with a protective film to use. In addition, the polarizing film is composed of a linear polarizing film and a retardation film = two: a protective film is attached to one or both sides of the polarizing film: "On the ellipsic film" In the present invention, an adhesive layer is formed, and an adhesive layer is usually formed on the retardation film side. The surface protective film is a film used for the purpose of protecting an optical film or the like as a protected body from surface damage or contamination. For example, various optical films such as a polarizing film, a retardation film, a light diffusion sheet, and a reflective sheet used in the production of a liquid crystal display I are used on the surface thereof (when the adhesive layer is provided on one side, it means The adhesive layer is on the opposite side, and the surface protective film is bonded to the surface, and after being bonded to the liquid crystal cell or the like, the surface protective film is usually removed.

The resin film to which the adhesive is attached is attached to the glass substrate and is not suitable for the laminate. When the resin film is peeled off from the glass substrate, the adhesive layer is peeled off along with the resin film, and the surface of the glass substrate where the agent layer is in contact with each other is hardly caused by the phenomenon that the paste remains or the like. The glass substrate can be easily reattached to the resin film with the adhesive. That is, the reworkability is excellent. [Optical laminate] The resin film of the adhesive of the present invention can be composed of an optical film to form a tree, An optical product is formed by laminating an adhesive on a glass substrate: 1 to laminate an optical film with an adhesive on a glass substrate to form an optical laminate, for example, from the above The agent tree 2 is closed to the film _ and the exposed adhesive layer is bonded to the surface of the glass substrate.

In addition, when I becomes 10 parts of Jing Yitian I, the durability is insufficient. τ [Industrial Applicability] Adhesive of the present invention The resin film of the agent can effectively suppress the electrification of the light material. Moreover, the antistatic property of the light-keeping period can be maintained for a long period of time after the production. The tree that adheres to the first time is, for example, the optical raft. Forming a resin film and obtaining a light that is not used by the liquid crystal by laminating on the glass substrate of the liquid crystal cell In the case of moist heat, the optical layered body absorbs/buffers the stress caused by the dimensional change of the optical film and the glass substrate by the adhesive layer, thereby reducing local stress concentration and suppressing The adhesion or peeling of the adhesive layer to the glass substrate, etc. At the same time, since the optical defects caused by the uneven stress distribution can be prevented, the white color is formed. Further, once the resin film with the adhesive is laminated on the glass If there is any unreasonable situation, even if the resin film and the adhesive are peeled from the glass plate, the surface of the glass substrate will rarely be sticky or smashed, and it can be used as a glass substrate again. In addition, the resin film with an adhesive can also be used as a surface protective film which is bonded to the surface of the optical film and protects the surface until use. An excellent antistatic effect can be imparted, for example, by adhering the optical film to the liquid crystal cell 320560 42 200920811 via an adhesive layer on the opposite side of the surface protective film, and protecting the surface When peeling, the generated static electricity can be changed: The resin film with an adhesive of the present invention can maintain the antistatic property for a long period of time while imparting high antistatic property, and also has excellent durability. The resin film with an adhesive is composed of an optical film to form a resin film, and can be applied to a liquid crystal display device. Further, the resin film with an adhesive can be suitably used as a surface protective film for protecting the surface of the optical film.
