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 showing excellent durability even when applied to an optical member such as a polarizing plate.SOLUTION: The pressure-sensitive adhesive composition comprises: a (meth)acrylate polymer (A) having a weight average molecular weight of 900000 to 3000000 and containing, as a monomer unit constituting the polymer, a monomer having an alicyclic structure; an active energy ray-curable component (B); and a silane coupling agent (C) having a mercapto group as a functional group to react with an organic material.
