[PROBLEMS] To balance (1) adhesive strength in a low-speed peeling area and a high-speed peeling area, (2) prevention of occurrence of adhesive residue, (3) excellent antistatic performance, and (4) rework performance. Provided is a surface protective film capable of simultaneously satisfying all required performances. An acrylic copolymer includes (A) a (meth) acrylic acid ester monomer having an alkyl group having C4 to C10 carbon atoms, (B) a copolymerizable monomer containing a hydroxyl group, and (C) a carboxyl. (D) a trifunctional or higher functional isocyanate compound, (E) a crosslinking retarder of a ketoenol tautomer, (F) A crosslinking catalyst, (G) an antistatic agent, (H) a polyether-modified siloxane compound having an HLB value of 7 to 12, and the (G) antistatic agent has a melting point of 30 to 80 ° C. Is an ionic compound that is solid at 30 ° C. [Selection figure] None |
