PURPOSE:To accomplish ready peeling without any problem of transfer, of the titled film by irradiating ultraviolet rays on said film 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 transparent plastic film base with a specific irradiation-crosslinkable adhesive followed by crosslinking by irradiation. CONSTITUTION:An adhesive film obtained by coating a transparent plastic film base (e.g. PE, PP) with a radiation-crosslinkable adhesive prepared by incorporating (A) 100pts.wt. of a liquid oligomer having in the molecule acryloyl group with (B) 5-100 (pref. 20-50)pts.wt. of a polyfunctional monomer containing methacryloyl group (e.g. 1,4-butamedial dimethacrylate) followed by crosslinking through irradiation is laminated on an adhered such as metal plate or aluminum sash. After the service termination, ultraviolet rays are irradiated on the back surface of the base film to cure said adhesive followed by peeling the adhesive film off the adhered.
