Document Type and Number:
Japanese Patent JP6106205
Kind Code:
B2
Abstract:
A pressure-sensitive adhesive composition comprising: a (meth)acryl-based polymer comprising (a1) 70% by weight or more of a monomer unit derived from an alkyl (meth)acrylate, (a2) 3 to 25% by weight of a monomer unit derived from an aromatic ring-containing (meth)acrylate, (a3) 0.1 to 8% by weight of a monomer unit derived from an amide group-containing monomer, (a4) 0.01 to 2% by weight of a monomer unit derived from a carboxyl group-containing monomer, and (a5) 0.01 to 3% by weight of a monomer unit derived from a hydroxyl group-containing monomer, the (meth)acryl-based polymer having a weight average molecular weight (Mw) of 1,000,000 to 2,500,000 and a weight average molecular weight (Mw)/number average molecular weight (Mn) ratio of 1.8 to 10; and a crosslinking agent, the pressure-sensitive adhesive composition containing 0.01 to 3 parts by weight of the crosslinking agent based on 100 parts by weight of the (meth)acryl-based polymer.
