PROBLEM TO BE SOLVED: To obtain a sheet having no so-called 'ink taken-off' phenomenon by forming a release layer of a mixture of an extender of a specific weight mixed in a resin. SOLUTION: A release layer, a design layer or a release layer, a design layer and an adhesive layer are sequentially laminated on a release sheet 2. Here, as the sheet 2, a polyvinyl chloride, a metal foil or the like is used. As the release layer 3, when a layer having properties of elongating a film according to a heat and a pressure is used, a polyvinyl butyral resin is preferably used. Further, it is good to mix an extender in the resin. As the extender, a barium sulfate or the like is used. Its good mixing amount is 10 to 30 pts.wt. to 100 pts.wt. of the resin. The design layer 4 is formed by double printing one or above colors of gravure printing inks. The ink is obtained by mixing a coloring pigment in the resin, and, in addition, a surfactant is added. The layers provided on the sheet 2 are provided normally by in-line printing with-a multicolor printer.
