The present invention aims to provide a thermal transfer image-receiving sheet which does not suffer from any cockle problem, during printing, associated with a printer or a dye transfer film used. The thermal transfer image-receiving sheet comprises a substrate sheet and, provided on at least one surface thereof in the following order, an intermediate layer and a receptive layer, the intermediate layer containing either an acrylic polyol or cellulose acetate butyrate. Further, the present invention provides a thermal transfer image-receiving sheet which has a capability of preventing curling and causes no damage to an image-receiving surface even when image-receiving sheets put on top of each other or one another are used. This thermal transfer image-receiving sheet comprises a back surface layer provided on a substrate sheet in its surface where no image is to be formed, the back surface layer containing an acrylic polyol.

Thermal transfer image-receiving sheet

A thermal transfer material and an image-forming method using the same are provided which can form a sublimation-transferred image, on a contemplated object, having neither dropouts nor unevenness, free from bleeding, and excellent in stabilities, that is, light fastness and fixability. The thermal transfer material comprises: a substrate; and a receptive layer separably provided on one surface of the substrate, the receptive layer containing a metal ion-containing compound. The image-forming method comprises the steps of: putting a thermal transfer material, comprising a substrate and a receptive layer separably provided on one surface of the substrate, on a dye layer so that the receptive layer comes into contact with the dye layer; heating the laminate to form an image on the receptive layer; and transferring the receptive layer with an image formed thereon onto an object, wherein the receptive layer contains a metal ion-containing compound and the dye layer contains a thermal diffusible dye capable of forming a chelate.
