PROBLEM TO BE SOLVED: To provide a surface protective film which has excellent antistatic performance, has excellent balance of adhesive force at peeling speeds in a low speed region and a high speed region, excellent durability performance and rework performance, and can prevent occurrence of defects such as recess due to external stress.SOLUTION: There is provided a surface protective film having an adhesive layer crosslinked with an adhesive composition formed on one surface of a resin film, where a (meth)acrylic polymer is formed of a copolymer of copolymerization of 55-97.5 pts.wt. of alkyl (meth) acrylate having an alkyl group having 4-10 carbon atoms, 1-30 pts.wt. of alkyl (meth) acrylate having an alkyl group having 14-18 carbon atoms, 0.1-15 pts.wt. of a hydroxy group-containing copolymerizable monomer, and 0.1-2 pts.wt. of a carboxyl group-containing copolymerizable monomer, with respect to 100 pts.wt. of the (meth)acrylic polymer; and an antistatic agent has a melting point of 30 to 50°C.SELECTED DRAWING: None |
