摘要:

A pressure-sensitive adhesive composition for an optical member is obtained by blending 100 parts by weight of an acrylic polymer, which contains 80 to 98.7 parts by weight of (a) a monomer constituted of an alkyl acrylate monomer having an alkyl group of 1 to 12 carbon atoms and/or an aromatic ring-containing acrylic monomer, 0.2 to 1.5 parts by weight of (b) an amide group-containing acrylic monomer and 1 to 5 parts by weight of (c) a hydroxyl group-containing acrylic monomer, with 0.12 to 1 part by weight of (d) an isocyanate-based curing agent having an isocyanurate skeleton as a curing agent, and is characterized by substantially containing no metal chelate-based curing agent. Accordingly, a pressure-sensitive adhesive composition, which has excellent heat resistance and wet heat resistance and whose aging time can be particularly shortened, is provided.
