PROBLEM TO BE SOLVED: To provide an ID card manufacture process by which an ID card being excellent in durability and forgery preventive capability, can be easily made, and of which the maintenance is simple. SOLUTION: For this heat transfer sheet, on the side having a release property of a releasable supporting body, a layer comprising of an acrylic based ultraviolet ray hardening resin, an intermediate layer comprising of a polyvinyl butyral resin of which the degree of polymerization is 1000 or higher or a thermally hardening resin of polybutiral, and a bonding layer comprising of a urethane modified ethylene ethyl acrylate copolymer and a polyacreylic ester copolymer, are provided in order. Then, after providing a transparent inorganic thin film on the ultraviolet ray hardening resin layer or the intermediate layer, a stamping is applied to form a transparent hologram, or the stamping is applied on the ultraviolet ray hardening resin layer or the intermediate layer, and a transparent inorganic thin film is provided to form the transparent hologram. Also on an image or a printed surface side of the base body wherein at least one being selected out of a certification-identification image, an attribute information image and a formed printing, is printed, a protective layer is formed by using the previously mentioned heat transfer sheet. |
