    (54) Image-receiving sheet for thermal transfer printing with an intermediate layer containing fine particles of thermosetting resin and fine particles of polyolefin resin


    (57) An image-receiving sheet for thermal transfer printing comprising a substrate, an intermediate layer and an image-­receiving layer, said intermediate layer and said image-­receiving layer being disposed in this order on said sub­strate, characterized in that said intermediate layer comprises a layer containing (a) fine particles of one or more kinds of resins selected from the group consisting of thermosetting resins and other resins having a softening point of higher than 150°C and (b) fine particles of a polyolefin resin as the main constituents and the amount of said fine particles (a) contained in the intermediate layer is in the range of from 5 to 90% by weight.
    The image-receiving sheet excells in the whiteness and opacity and exhibits an excellent recording sensitivity. The image-receiving sheet provides high quality images accompanied with no missing dot when used in a thermal transfer printing system wherein a thermally sublimable dye is utilized.
