Abstract:
1. A pressure-sensitive adhesive composition for an optical member, obtained by blending: 100 parts by weight of an acrylic polymer containing: 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, said pressure-sensitive adhesive composition substantially containing no metal chelate-based curing agent, said isocyanate-based curing agent (d) having an isocyanurate skeleton being a tolylene diisocyanate-based curing agent, and said alkyl acrylate monomer having an alkyl groups of 1 to 12 carbon atoms comprises an alkyl acrylate monomer having an alkyl group of 1 to 3 carbon atoms and an alkyl acrylate monomer having an alkyl group of 4 to 12 carbon atoms.
