PRESSURE-SENSITIVE ADHESIVE COMPOSITION AND PRESSURE-SENSITIVE ADHESIVE SHEET

摘要

A pressure-sensitive adhesive composition including: a (meth)acrylate copolymer (A) obtained by copolymerizing a (meth)acrylate and a reactive group-containing monomer, such that a ratio of the reactive group-containing monomer (constituent unit derived from the monomer) in the copolymer ranges from 0.01 to 15 wt %; a polyrotaxane (B) having at least two cyclic molecules and a linear-chain molecule passing through opening portions of the cyclic molecules wherein the cyclic molecules have each one or more reactive groups and the linear-chain molecule has blocking groups at both ends thereof; and a crosslinking agent (C) having a reactive group capable of reacting with the reactive group of the (meth)acrylate copolymer (A) and with the reactive group of the polyrotaxane (B).
