    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.

    摘要： An object is to provide a pressure-sensitive adhesive composition for a polarizer that is excellent in durability and simultaneously is excellent in prevention of leakage of light, without the use of a high-energy light ray. The pressure-sensitive adhesive composition for a polarizer contains components (A) to (C) and having a gel fraction of 91% or more. (A) 100 parts by weight of an acrylic polymer that is obtained by copolymerizing at least the following monomer components (a1) to (a3), and has a weight average molecular weight of 500,000 to 2,000,000 and a ratio (Mw/Mn) of the weight average molecular weight (Mw) to a number average molecular weight (Mn) of 8 or less: (a1) 45 to 94.9% by mass of an alkyl (meth)acrylate ester monomer, (a2) 0.1 to 5% by mass of a carboxyl group-containing monomer, and (a3) 5 to 50% by mass of a benzene ring-containing monomer; (B) 4 to 12 parts by weight of a tolylene diisocyanate crosslinking agent; and (C) 0.05 to 1 part by weight of a silane coupling agent that has reactivity with a carboxyl group, wherein the benzene ring-containing monomer of the monomer component (a3) is 5 times or more in terms of mole of the tolylene diisocyanate crosslinking agent of the component (B).
