PURPOSE:To enable the titled material to remain stable in preservation under hot and humid environment and enhance thermal conductivity of an ink layer by using an anti-sticking layer, providing a hardened film of a siloxane having a radial-polymerizable double bond on the back side of a base film. CONSTITUTION:A hardened film of a siloxane having a radical-polymerizable double bond is a film obtained by hardening the siloxane by irradiating with UV rays, electron rays or the like. The siloxane having the radical- polymerizable double bond may be equivalent to a monomer, an oligomer or a prepolymer. A film-forming material comprising at least the siloxane is applied to a base film by a conventional method, and is irradiated with UV rays, electron rays or the like to provide a film. Since little thermal loss arises from the protective layer thus provided, clear printed images can be obtained even when printing speed is enhanced, and accordingly, it is possible to cope with a high-speed printing. |
