PROBLEM TO BE SOLVED: To provide an antistatic acrylic adhesive which solves problems in an optical use of a conventional antistatic adhesive caused by static electrification upon peeling, and which has excellent transparency and removability.SOLUTION: The antistatic acrylic adhesive comprises: an acrylic copolymer (A) having a hydroxyl group and an ethylene oxide chain as a side chain (excluding, however, an acrylic copolymer having a carboxyl group); an ionic compound (B) containing one cation selected from the group consisting of lithium, iron, copper, sodium, potassium and quaternary ammonium; and a curing agent (C) that is a trifunctional isocyanate compound. The acrylic copolymer (A) is prepared by solution polymerization of 1 to 30 wt.% of a monomer having a hydroxyl group, 1 to 60 wt.% of an acrylic monomer having an ethylene oxide chain, and a monomer having 2-ethylhexyl (meth)acrylate. A dry film of the adhesive has a surface resistance of 9×10&OHgr;/square or lower. |
