PURPOSE:To enhance characteristics such as strength, folding endurance or the like by constituting the subject sheet of a base material layer composed of a fabric or a nonwoven fabric and the image receiving layer provided on said base material layer and providing a microporous layer composed of a specific material to the entire surface of the base material layer. CONSTITUTION:A base material layer 1 consists of a fabric or a nonwoven fabric and the image receiving layer 2 provided thereon is composed of a composite layer consisting of a microporous layer of polyamide or polyurethane and the thin highly color-developable receiving layer provided on said microporous layer or a composite layer consisting of the microporous layer of polyamide or polyurethane and the thermal ink layer provided on said microporous layer and, in case of both image receiving layers, the microporous layer of polyamide or polyurethane is used as a base. The microporous layer is formed by a wet film forming method and polyamide or polyurethane penetrates in the yarns 3 of the surface of the base material layer and the interstices between them to be capable of being integrated with the base material layer. By this method, the use in a thermal head printer becomes possible and strength, the touch, durability, folding endurance and water resistance can be enhanced. |
