PRESSURE-SENSITIVE ADHESIVE COMPOSITION, PRESSURE-SENSITIVE ADHESIVE AND PRESSURE-SENSITIVE ADHESIVE SHEET

摘要

PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition, a pressure-sensitive adhesive and a pressure-sensitive adhesive sheet having high adhesiveness to an optical member such as a polarizing plate as well as having excellent durability.SOLUTION: The pressure-sensitive adhesive composition comprises: a (meth)acrylate polymer (A) having a weight average molecular weight of 800000 to 3000000 and containing a monomer having an alicyclic structure as a monomer unit constituting the polymer; a crosslinking agent (B); and a silane coupling agent (C) having a mercapto group as a functional group to react with an organic material.
