PURPOSE:To ensure excellent releasability of an ink layer, obtain a favorable printed image and enable safe and easy production, by providing an anchor layer containing a watersoluble polymer between a base and a heat-fusible coloring material layer. CONSTITUTION:A water-soluble polymer to be used may be, for example, polyvinyl alcohol, polyvinyl pyrrolidone, gelatin, carboxylmethyl cellulose, methyl cellulose, polyethylene oxide, gum arabic, a water-soluble polyester, water-soluble polyurethane, a water-soluble acrylic polymer or a watersoluble polyamide. The water-soluble polymer preferably has a softening point of at least 100 deg.C, the content thereof is ordinarily at least 5wt.%, and preferably contains a filler. The average particle diameter of the filler is ordinarily 0.2-3mum, and the film thickness of an anchor layer is ordinarily 0.05-3mum. |
