ADHESIVE COMPOSITION, ADHESIVE LAYER, POLARIZING FILM HAVING ADHESIVE LAYER, AND IMAGE FORMATION DEVICE

摘要

Provided is an adhesive composition that contains (A) an aromatic ring-containing (meth)acrylic polymer that contains an aromatic ring-containing alkyl (meth)acrylate as a monomer unit, and (B) an ionic compound having an anionic moiety and a cationic moiety. The anionic moiety is preferably at least one type of anionic moiety represented by general formula (1): (CnF2n+1SO2)2N- (1)(in general formula (1), n is an integer between 1 and 10), general formula (2): CF2(CmF2mSO2)2N- (2) (in general formula (2), m is an integer between 2 and 10), or general formula (3): -O3S(CF2)l SO3 - (3) (in general formula (3), l is an integer between 3 and 10).
