[0159] From this experimental example, the following matters are known. The present invention has high adhesiveness. The present invention has flexibility to the extent that it can follow the deformation of the adherend under a heated environment, and thus has high moisture and heat resistance. When DMDO, which is a compound having two or more mercapto groups, is used, the flexibility and adhesiveness are low.

Abstract

Provided is a curable resin composition exhibiting high adhesion durability. The curable resin composition contains: a (meth)acrylate oligomer (A) selected from the group consisting of urethane-based (meth)acrylate oligomers, polyester-based (meth)acrylate oligomers, polyether-based (meth)acrylate oligomers, epoxy-based (meth)acrylate oligomers, diene polymer-based (meth)acrylate oligomers, and oligomers having a backbone of the hydrogenated product of a diene polymer-based (meth)acrylate; a (meth)acrylate (B) exhibiting a homopolymer glass transition temperature of -100 DEG C to 60 DEG C; one or more compounds (C) having one mercapto group per molecule, the compound(s) being selected from the group consisting of alkanethiols and carboxythiols; and a photopolymerization initiator (D).

Description

technical field [0001] The present invention relates to curable resin compositions. Background technique [0002] There are resistive film type, capacitive type, electromagnetic induction type, optical type, etc. for touch panels mounted on displays such as LCDs. A decorative panel for improving the design of the appearance or an icon sheet for designating a touch position may be attached to these touch panels. A capacitive touch panel has a structure in which a transparent electrode is formed on a transparent substrate, and a transparent plate is bonded thereon. [0003] In recent years, the glass of displays such as LCDs has gradually become thinner. When the glass becomes thinner, the LCD becomes easily deformed by external stress. When laminating thin glass displays such as LCDs with optical functional materials such as acrylic plates and polycarbonate plates, due to the difference in linear expansion between glass and acrylic plates, the molding of plastic molding ma...
