PURPOSE:To improve the tolerance against surface stain and/or surface defect, by providing an intermediate layer above a heat-sensitive color generating layer which is mainly composed of aqueous high molecules, and a protective layer above the intermediate layer which is laminated with a high molecular film attached with an adhesive agent, and further a layer of an adhesive agent and a peel pasteboard on the reverse surface of a supporting member. CONSTITUTION:Over a supporting member 5 is applied a heat sensitive color generating liquid, for example, by 6.0g/m<2> (in solid). After drying, a heat sensitive color generating layer 4 is formed, onto which a polyvinyl alcohol liquid is coated by 3.0g/m<2> (in solid) and dried to be an intermediate layer 3. Thereafter, a high molecular film 1 using an acrylic acid ester system as an adhesive agent, that is, polyethylene terephthalate is attached onto the surface of the intermediate layer 3, which is subjected to the cold lamination. Then, an adhesive agent layer 6 and a peel pasteboard 7 are attached to the reverse surface of the supporting member 5 for adhering process. The heat sensitive color generating layer 4 can be easily obtained by being coated in a well- known manner with an application liquid having a color generating element and a binder added with other additives, e.g., sensitizing agents, smoothing agents or the like upon necessity. |
