PURPOSE:To improve the accepting aptitude of thermal transfer printing in the rear face of a supporting body by consisting of a water resistant covering layer and a back coat layer and containing a specific amount of an ionomer resin in the back coat layer. CONSTITUTION:The water resistant covering layer made of a polyolefin resin and the back coat layer containing 5-50% ionomer resin on the rear covering layer are provided on the both faces of a substrate made of a sheet-like material. For example, natural pulp paper and synthetic pulp paper, mixed paper of them, or the like and various combination papers are used as the sheet-like material. A sizing agent, a fixing agent, a paper pulp reinforcement, a filler, an antistatic agent or the like used for paper making are added and combined in the base papers. The polyolefin resin is selected from a single polymer of ethylene, alpha-olefin, propylene or the like, two or more kinds of copolymer of olefin. And the ionomer resin is made by actuating a metallic cation such as Na, Zn to a base copolymer of ethylene with acrylic acid, methacrylic acid or the like. |
