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.degree. C. to 120.degree. 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.degree. C.
