PURPOSE:To accomplish ready peeling without any problem of transfer, of the titled film by irradiation on said film to cure the adhesive thereon after its service termination which protected the surface of an adhered such as metal plate by lamination thereon of a film prepared by coating a base with a specific adhesive. CONSTITUTION:An adhesive film obtained by coating a base with an adhesive comprising (A) 100pts.wt. of an acrylic copolymer with a glass transition point -30-30 deg.C and weight-average molecular weight >=50,000 and (B) 50-200pts.wt of a radiation-curable polyfunctional liquid resin (pref. with >=4 acryloyl groups, or an oligomer) is laminated on an adhered such as metal plate or aluminum sash. After the service termination, the back surface of the base is subjected to radiation to cure said adhesive, followed by peeling the adhesive film off the adherend.
