    摘要： A thermal transfer image-receiving sheet comprising (1) a support comprising (a) a surface layer comprising a biaxially stretched film of a thermoplastic resin containing from 2 to 60% by weight of titanium dioxide fine powder and (b) a base layer comprising a biaxially stretched microporous film of a thermoplastic resin containing from 10 to 45% by weight of an inorganic fine powder and (2) an image-receiving layer provided on surface layer (a) of support (1), in which support (1) has a void volume of from 30 to 60% and a density of from 0.50 to 0.78 g/cm.sup.3, and surface layer (a) of support (1) has a center-line average roughness of not more than 0.5 .mu.m and a Bekk's smoothness of from 4,000 to 100,000 sec. The thermal transfer image-receiving sheet has an excellent cushioning effect due to the number of microvoids present in the support thereof and high sensitivity in a middle tone region owing to the titanium dioxide present in the surface layer of the support to provide a clear image having a high density even with reduced printing energy.

    摘要： A support for a dye transfer type thermosensitive printing sheet is disclosed, which comprises a porous film base having a biaxially stretched film of a thermoplastic resin containing an inorganic fine powder having adhered thereon a thermoplastic resin film having a centerline-average roughness of not more than 0.5 .mu.m as a surface layer on which a dye transfer type thermosensitive printing layer is to be provided, said surface layer having a thickness of from 0.3 to 1.5 .mu.m and a Bekk's smoothness of from 2500 to 7000 seconds, and said support having an opacity of not less than 70%, a density of not more than 0.91 g/cm.sup.3, and a compression ratio of from 15 to 35% under a stress of 32 kg/cm.sup.2. A dye transfer type thermosensitive printing sheet using the support of the invention has excellent surface smoothness and exhibits considerable compressibility and, therefore, shows improved adhesion or contact with a printing head to form an image rich in gradation.
