ADHESIVE COMPOSITION, ADHESIVE LAYER, ADHESIVE SHEET AND OPTICAL FILM

摘要

An adhesive composition comprises: 100 parts by mass of a polymer (A) which has a glass transition temperature of less than 0°C; 0.05 to 50 parts by mass of a (meth)acrylic polymer (B) which has a weight average molecular weight of 1000 or more and less than 30000 and which includes a monomer having a polyoxyalkylene skeleton as a monomer unit; and 0.01 to 40 parts by mass of a (meth)acrylic polymer (C) which is represented by general formula (1) and which includes, as a monomer unit, a (meth)acrylic monomer that has a glass transition temperature of a homopolymer of 0°C or more. CH2=C(R1)COOR2 (1) [In formula (1), R1 is a hydrogen atom or a methyl group, and R2 is an alkyl group having 1-12 carbon atoms or an alicyclic hydrocarbon group.] However, the (meth)acrylic polymer (C) does not include a polyoxyalkylene skeleton.
