Zusammenfassung:	PROBLEM TO BE SOLVED: To maintain a clear printed state without deformation caused by embrittlement or shrinkage in the case of applying heat in post-processing or the like by developing specified internal stress of a film laminated to a metallic sheet having a base layer composed of a thermoplastic resin film and a hardening heat-resistant layer composing an outermost layer. SOLUTION: A heat-resistant hardening resin 4 composing an outermost layer is provided on one side of a thermoplastic resin film layer 1. In practical use, a printing ink layer 2 and an adhesive layer 3 composed of hardening resin is formed on the opposite side thereof for laminating the side of the adhesive layer 3 to a metallic sheet M through dry lamination, a thermal laminating, or the like. In this case, the thermoplastic resin film layer 1 composes base film, which enables clear, beautiful multiple printing. And a film having internal stress of 0.25 kg/mm or lower at 86-300 deg.C in a laminated state with the hardening heat-resistant layer 4 combined is used.
