Abstract

PROBLEM TO BE SOLVED: To provide an adhesive composition which has excellent antistatic performance, an excellent balance of adhesiveness at peeling rates in a low speed region and a high speed region, and further excellent durability performance and rework performance, and to provide an adhesive film and a surface protective film.SOLUTION: There is provided an adhesive composition containing an antistatic agent, which comprises: 100 pts.wt. of an acrylic polymer containing as a main component an alkyl (meth)acrylate having a C4 to C10 alkyl group; 85 to 98.5 pts.wt. of an alkyl (meth)acrylate being a main component; 0.1 to 15 pts.wt. of a hydroxyl group-containing copolymerizable monomer; 0.1 to 2 pts.wt. of a carboxyl group-containing copolymerizable monomer; and 0.1 to 5 pts.wt. of a crosslinking agent. The acrylic polymer has an acid value of 0.01 to 8.0. The antistatic agent is an ionic compound having a melting point of 30 to 50°C and contains a polyether-modified siloxane compound having an HLB value of 7 to 15.
