Patent ID: 8513363

Claim:
An adhesive composition, comprising: 100 parts by weight of a (meth)acrylic copolymer having a weight average molecular weight of about 150,000 to about 950,000 g/mol; about 0.05 to about 5 parts by weight of a carbodiimide crosslinker, based on 100 parts by weight of the (meth)acrylic copolymer; and about 0.001 to about 5 parts by weight of an imidazole compound represented by Formula 1, based on 100 parts by weight of the (meth)acrylic copolymer: wherein: in Formula 1, R′, R 2 , and R 3 are each independently a hydrogen atom, a halogen atom, or a substituted or unsubstituted C1 to C10 straight or branched alkyl group, the adhesive composition prepares an adhesive layer for a surface protective film, and the adhesive layer has an adhesive strength of about 0.05 to about 0.3 N/25 mm according to JIS Z0237.
