Description of the Invention: [Technical Fields of the Invention] Field of the Invention The present invention relates to an active energy ray that can be followed by various plastic films or sheets by irradiating an active energy ray such as an electron beam or an ultraviolet ray. The type of the composition of the present invention is suitable for use in a thin layer of adherend which is followed by a film or sheet made of plastic, and is suitable for use in manufacturing various optical films or sheets used for liquid crystal display elements and the like, and This specialized field of technology is loved. Further, 'in the present specification, (fluorenyl) acrylate means acrylate and/or mercapto acrylate, and (mercapto) propylene group means acryl fluorenyl and/or mercapto propyl sulfonate, (fluorenyl) The acrylic acid means acrylic acid and/or methacrylic acid. In addition, in the following, if there is no need to express it specifically, the plastic film or sheet will be summarized as "Plastic thin amine cage:, 矣+, #必# 1 a 胗溥膜寺", and the film or sheet will be The summary is indicated by "film, etc."

CJ BACKGROUND OF THE INVENTION Previously, a laminate of a thin layer of adherends bonded to a plastic sheet or the like, or a single layer of adherends bonded with a plastic thin lining and a thin layer of other materials was used. The main method is a dry lamination method in which a solvent-based adhesive composition containing a vinyl acetate s-ethylene copolymer or a polyamine ruthenium sulphate polymer is coated on a second layer of a binder. k , After the island, the second thin layer of adherend is pressure-bonded using a nip roll or the like. In general, in order to make the coating amount of the composition uniform, the adhesive composition of 201109405 used in the method contains a large amount of solvent, so that a large amount of solvent money is volatilized during drying, and toxicity and seizure become safe. problem. Also, «the composition of the agent is adhered to the thin layer of the adherend, and the film is adhered to the post-processing process for the heat sealing of the laminated film and the groove process of the groove. There is a problem of peeling between objects. In order to solve such problems, it has been studied to use a solventless adhesive composition as an adhesive composition. As the solventless adhesive composition, a two-liquid type after-treatment composition and an adhesive composition hardened by an active energy ray of an ultraviolet ray or an electron ray are widely used. As a two-liquid type adhesive composition, a so-called polyamine hydrazine which is a hardening agent by using a polymer having a trans group at the terminal as a main component and a polyisocyanate compound having an isocyanate group at the terminal is mainly used. An acid ethyl ester-based adhesive composition. However, this composition has a drawback that it takes a long time to harden, and therefore there is a problem in productivity, that is, a post-processing process in which a thin layer of the adherend is not adhered immediately after entering the grid process. On the other hand, since the hardening speed is fast and the productivity is excellent, recently, the active energy ray-curable adhesive composition has been attracting attention. On the other hand, because of the advantages of thinness, light weight, and power saving, the liquid crystal display device is used from a small navigation device such as a car navigation system, a mobile phone, and a pda, to a word processor or a personal computer. Television image receivers are popular. In recent years, an active energy ray-curable adhesive has been gradually used for bonding various optical films and the like used in the liquid crystal display device. 201109405 As an optical film, etc., a polarizing plate, a retardation film, a viewing angle compensation film, a twisting film, an antireflection film, an antiglare film, a lens sheet, and a diffusion sheet are used, and various types are used. Plastic. Among these plastics, 'as a polarizing plate, and particularly, those which are reused include polyvinyl alcohol and triethyl fluorenyl cellulose. These plastics contain hydroxyl groups and are highly hydrophilic compared to conventional plastics. As an active energy ray-curable adhesive composition for a polarizing plate, a photoradical polymerization type composition using photoradical polymerization, a photocationic polymerization type composition by photocationic polymerization, and photo-radical polymerization using A mixed composition of photocationic polymerization. As a photo-radical polymerization type composition, a composition is known (patent document D or the like contains a radical polymerizable compound containing a polar group such as a hydroxyl group or a radical in a specific ratio; and a radical polymerization which does not contain a polar group; However, since the shrinkage of the composition at the time of curing is large, stress is generated at the interface depending on the type of the adherend, and it is difficult to obtain sufficient peel strength. Further, in order to solve this problem, a molecular weight containing a large molecular weight is considered. A composition of ethyl amide (ethyl) acrylate (for example, Patent Document 2). However, since the viscosity of the composition is increased, there is a problem that film coating or the like cannot be applied according to the coating device. Although the shrinkage stress at the time of hardening can be alleviated by improving the flexibility of the composition to be engraved, the heat resistance or water resistance of the adhesive composition is deteriorated, and strict durability is required. For the purpose, there may be problems of peeling off, foaming, and cracking 201109405. As a photocationic polymerization type composition, it is known that it will not contain an aromatic ring. The group of ring _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The composition, because the composition is relatively small at the time of hardening (4), has the advantage of being able to suppress the stress generated at the interface. It is widely known that photocationic polymerization produces polymerization barriers caused by water or test substances, and is high in humidity. In the environment, a substrate containing a large amount of water, and a substrate having a secret surface, it is difficult to obtain a sufficient (four) ft shape of the strength, and 'the composition contained in the polyfunctional epoxy resin as a domain, Nengcheng small polymerization resistance causes the effect of the decrease in hardenability. However, if the viscosity of such a group rises, there is a problem that the coating device cannot be applied to the film. As a mixed composition, it is known that it has isomeric acid. a composition of a (fluorenyl) acrylate acrylate, a lipid s epoxide compound, a radical group-containing compound, and a photoacid generator of a base ring skeleton (Patent Document 5); and having two or more epoxy groups and At least one of the groups is an alicyclic epoxy group epoxy a composition of an epoxy resin, an epoxy resin having two or more epoxy groups and having no alicyclic epoxy group, a photocationic polymerization initiator, and a polymerizable monomer (Patent Document 6); and having two or more (fluorenyl) acrylate-based compound, compound having a hydroxyl group and a fluorenyl group, a cationically polymerizable compound having a (meth)acryl group, a photoradical polymerization initiator, and a photocationic polymerization initiator The composition (Patent Document 7), etc. Although these compositions are mixed to solve the shrinkage at the time of hardening and 6 201109405, the polymerization caused by moisture (4), (4) The inventors' research clearly understands the following The problem disclosed in Patent Document 5 contains a (meth)propene (tetra) compound having a heterotrimeric acid ring skeleton as an essential component, but according to the study of the present inventors, it is clear that The composition contains a large amount of the (meth)acrylic acid _ having two or more (fluorenyl) acrylonitrile groups, because shrinkage at the time of hardening is large*, and stress at the interface cannot be suppressed, and therefore, Depending on the substrate, it may be difficult to obtain sufficient peel strength. In the composition disclosed in Patent Document 6, although the composition is mixed in a conceptual form, only the invention of the above concept is described, and in the examples, only the composition composed of the photocationic polymerizable monomer is disclosed. , but lack specificity. In the composition disclosed in Patent Document 7, a cationically polymerizable compound having a (meth)propyl group is contained as a necessary component in a specific ratio, and = according to the study of the present inventors, it is clear that a large amount of & ^ In the case of this compound, since the shrinkage at the time of hardening is not so large, the stress on the both sides cannot be suppressed, and therefore, a sufficient degree of separation of the substrate is obtained depending on the substrate.
