Patent ID: 8124706

Claim:
An adhesive composition comprising: 100 parts by weight of (a) a (meth)acrylic monomer, and 10 to 400 parts by weight of (b) a (meth)acrylic polymer containing a (meth)acrylic ester as a main monomer, wherein the weight-average molecular weight of the (meth)acrylic polymer (b) in terms of standard polystyrene, as measured by GPC, is in the range of 50,000 to 800,000, and the (meth)acrylic polymer (b) has 0.3 to 1 end group represented by the formula (1) based on one polymer chain, wherein R 1 is an alkyl or aryl group of 1 to 12 carbon atoms, R 2 is a hydrogen atom or a methyl group, and R 3 is a hydrogen atom, an alkyl or aryl group of 1 to 12 carbon atoms.
