PRESSURE-SENSITIVE ADHESIVE COMPOSITION AND PRESSURE-SENSITIVE ADHESIVE TAPE

摘要

PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition which has pressure-sensitive adhesiveness at ordinary temperature and undergoes a curing reaction to develop increased bonding strength when heated and a pressure- sensitive adhesive tape coated therewith. SOLUTION: There is provided a pressure-sensitive adhesive composition comprising a (meth)acrylate copolymer comprising a (meth)acrylic ester (a) in which the ester moiety is an aliphatic or aromatic hydrocarbon compound, an ether-bond-containing (meth)acrylic ester (b) and a functional-group-containing monomer (c) and a phenolic resin. This composition is applied to at least either surface of a support 2 to form a pressure-sensitive adhesive layer 3, and a release layer 4 is formed thereon to form a pressure-sensitive adhesive tape 1. The mixing ratio among components (a), (b) and (c), a/b/c, is (0-94)/(5-99.9)/(0.1-20).
