ADHESIVE COMPOSITION FOR OPTICAL APPLICATIONS, ADHESIVE LAYER FOR OPTICAL APPLICATIONS, OPTICAL MEMBER, POLARIZING PLATE, AND IMAGE DISPLAY DEVICE

摘要

The purpose of the present invention is to provide: an adhesive composition for optical applications, which is capable of suppressing luminance unevenness without deteriorating the contrast characteristics in optical applications, and which can be used for optical members and prevents the optical members from separation in a reliability test; an adhesive layer; an optical member; an image display device and the like. An adhesive composition for optical applications, which contains 100 parts by weight of a modified (meth)acrylic graft polymer and 0.01-1.80 parts by weight of an isocyanate crosslinking agent, is prepared. The modified (meth)acrylic graft polymer is obtained by graft polymerizing chains, each of which contains a cyclic ether group-containing monomer, to the trunk polymer, and contains, as constituent components, an alkyl (meth)acrylate, a cyclic ether group-containing monomer, and a non-cyclic ether group-containing monomer. The modified (meth)acrylic graft polymer contains 8-40 parts by weight of the non-cyclic ether group-containing monomer per 100 parts by weight of the total of other monomer components that constitute the trunk polymer. An adhesive layer for optical applications, which is formed from the composition, an optical member, an image display device and the like are also produced.
