Thermal transfer image-receiving sheet

Abstract

A thermal transfer image-receiving sheet having (1) a support of (B) a base layer which is a biaxially stretched microporous film of a thermoplastic resin containing from 10 to 45% by weight of an inorganic fine powder and (A) a surface layer which is a biaxially stretched film of a thermoplastic resin having a three-dimensional center-plane average roughness (Ra) of not more than 0.5 .mu.m, surface layer (A) having a spatial average wavelength (.lambda.a), defined by the equation .lambda.a=2.pi.Ra/.DELTA.a, where Ra is the three-dimensional center-plane average roughness and S.DELTA.a is the three-dimensional average slope, of not more than 100 .mu.m and a gloss of not less than 93% as measured at 75.degree. according to JIS P-8142 and (2) an image-receiving layer provided on the surface of the surface layer (A). The image-receiving sheet provides a clear image having high density, high gloss, and reduced rough feeling even using reduced printing energy.
