(57) [Summary] [Structure] (1) Ethylenically unsaturated carboxylic acid monomer, (2) Ethylenically unsaturated epoxy group-containing monomer, (3) Ethylene Selected from the group consisting of saturated tertiary amine monomers, (4) (meth) acrylic acid alkyl ester monomers and ethylenically unsaturated monomers copolymerizable with (meth) acrylic acid alkyl ester monomers. In addition, an emulsion-type acrylic pressure-sensitive adhesive obtained by copolymerizing at least one kind is applied and dried to form a pressure-sensitive adhesive layer, and then the pressure-sensitive adhesive layer is placed inside and wound into a roll for surface protection. Obtain an adhesive film. [Effect] A pressure-sensitive adhesive film for surface protection which is excellent in non-staining property and rewinding property of the adherend surface can be obtained without using a special soft vinyl chloride film. |
