Abstract:
A pressure-sensitive adhesive composition comprising (A) a (meth)acryl-based polymer, (B1) an ionic compound comprising a cation component and an anion component having an organic group of three or more carbon atoms, and (B2) an ionic compound comprising a cation component and an anion component having an organic group of two or less carbon atoms. The anion component having an organic group of three or more carbon atoms is preferably at least one of anion components represented by formula (1): (CnF2n+1SO2)2N− (1) in formula (1), n is an integer of 3 to 10, formula (2): CF2(CmF2mSO2)2N− (2) in formula (2), m is an integer of 2 to 10, formula (3): −O3S(CF2)lSO3− (3) in formula (3), l is an integer of 3 to 10, and formula (4): (CpF2p+1SO2)N−(CqF2q+1SO2) (4) in formula (4), p and q are each an integer of 2 to 10.
