OPTICAL ADHESIVE, OPTICAL ADHESIVE TAPE, AND LAYERED BODY

摘要

The present invention provides an optical adhesive which does not become clouded even when exposed to high temperature and humidity, which also has excellent antifoaming properties or workability, and which does not degrade a transparent electrode such as one comprising ITO. Another purpose of the present invention is to provide an optical adhesive tape and a layered body manufactured using the optical adhesive. The present invention is an optical adhesive containing: a (meth)acrylic polymer having a molecular weight distribution (Mw/Mn) of 1.05-2.5 obtained by copolymerization by living radical polymerization of a monomer mixture including a) 60-95 parts by weight of alkyl (meth)acrylate having a C1-14 alkyl group, b) 0.1-1 part by weight of a monomer containing a carboxyl group, and c) 10-30 parts by weight of a monomer containing a hydroxyl group, an amino group, or an amide group; and a crosslinking agent; the alkyl (meth)acrylate a) having a C1-14 alkyl group including (meth)acrylate having a bicyclo ring structure.
