ABSTRACT:
An image-receiving sheet for melt thermal transfer recording is disclosed, including: a support (I) comprising (i) a substrate layer (A) made of a stretched film having microvoids formed therein, said stretched film of substrate layer (A) is obtained by stretching a propylene resin film comprising a propylene resin in an amount of from 65 to 95% by weight and inorganic fine powder having a specific surface area of from 10,000 to 40,000 cm.sup.2 /g and an average grain diameter of from 0.5 to 2.3 .mu.m in an amount of from 5 to 35% by weight, (ii) a surface layer (B) made of a stretched propylene film comprising a propylene resin in an amount of from 35 to 65% by weight and inorganic fine powder having a specific surface area of from 25,000 to 300,000 cm.sup.2 /g and an average grain diameter of from 0.07 to 0.9 .mu.m in an amount of from 35 to 65% by weight laminated on one side of said substrate layer (A) and (iii) a back surface layer (C) made of a stretched propylene film comprising a propylene resin in an amount of from 35 to 90% by weight and inorganic fine powder having a specific surface area of from 10,000 to 40,000 cm.sup.2 /g and an average grain diameter of from 0.5 to 2.3 .mu.m in an amount of from 10 to 65% by weight laminated on the opposite side of said substrate layer (A); a water-soluble primer layer (IIa, IIb) coated on the surface layer (B) side of the support (I) or on both sides of the support (I), and a pulp paper layer (IV) having a thickness of from 40 to 250 .mu.m and a Taber stiffness of from 1 to 60 g.multidot.f.multidot.cm laminated on the back surface layer (C) side of the support (I) via an adhesive layer (III).
