Title:
PRESSURE-SENSITIVE ADHESIVE COMPOSITION, PRESSURE-SENSITIVE ADHESIVE AND PRESSURE-SENSITIVE ADHESIVE SHEET
Document Type and Number:
Japanese Patent JP2014152317
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition, a pressure-sensitive adhesive and a pressure-sensitive adhesive sheet giving no adverse influence of an acid component on an adherend such as a transparent conductive film and having excellent durability.SOLUTION: The pressure-sensitive adhesive composition comprises: a (meth)acrylate polymer (A) having a weight average molecular weight of 1500000 to 2500000, containing, as monomer units constituting the polymer, a monomer having a hydroxyl group and a monomer having an aromatic ring, and containing no monomer having a carboxyl group; and an isocyanate-based crosslinking agent (B). The (meth)acrylate polymer (A) contains, as monomer units constituting the polymer, 1 to 10 mass% of monomers having a hydroxyl group and 1 to 10 mass% of monomers having an aromatic ring.
