The photocurable pressure-sensitive adhesive composition, photocurable pressure-sensitive adhesive layer, and a light-curing adhesive sheet

摘要

PROBLEM TO BE SOLVED: To provide a photocuring adhesive composition capable of forming an adhesive layer which exhibits no paste protrusion at normal temperature and normal pressure, develops a sufficient initial adhesive force by drying and crosslinking, easily cures by light irradiation, has a high peel resistance, and has a good heat resistance; and to provide a photocuring adhesive layer, a photocuring adhesive sheet and the like.;SOLUTION: The photocuring adhesive composition is prepared which comprises a graft polymer obtained by graft polymerizing a chain containing a cyclic ether-containing monomer to a (meth)acrylic polymer, a cationic photopolymerization initiator, and a phenol resin.;COPYRIGHT: (C)2012,JPO&INPIT
