1. A thermal transfer dye image-receiving sheet comprising:
- a substrate sheet consisting of an oriented thermoplastic film comprising, as principal components, a polyolefin resin and inorganic particles, anda dye-receiving resin layer formed on a surface of the substrate sheet and comprising a resin capable of receiving a thermally transferable dye for forming dye images,the substrate sheet exhibiting thermal shrinkages of 1.50% or less in the longitudinal direction and 0.50% or less in the transverse direction of the substrate sheet when heated from a temperature of 20°
C. to a temperature of 120°
C., and having tensile moduli of elasticity of 50.0 MPa or less in the longitudinal direction and 100.0 MPa or less in the transverse direction of the substrate sheet, determined at a temperature of 120°

Abstract
A thermal transfer dye image-receiving sheet having a high resistance to curling and capable of smoothly travelling through a printer, and recording thereon dye images, includes a substrate sheet formed from a polyolefin resin and inorganic particles and a dye receiving resin layer formed on the substrate sheet, the substrate sheet having a longitudinal thermal shrinkage of 1.5% or less and a transversal thermal shrinkage of 0.5% upon heating from 20° C. to 120° C., and a longitudinal tensile elastic modulus of 50 MPa or less and a transversal tensile elastic modulus of 100 MPa or less at 120° C.
