A thermal transfer dye image-receiving sheet capable of receiving clear, uniform colored images without a formation of curls and wrinkles therein, comprising (A) a substrate sheet composed of (a) core sheet having a thermal shrinkage Y₃ , (b) a front coated thermoplastic film layer having a thickness T₁ and a thermal shrinkage Y₁ , and (c) a back coated thermoplastic film layer having a thickness T₂ and a thermal shrinkage Y₂ , the T₁ , T₂ , Y₁ , Y₂ and Y₃ satisfying the following relationships (1) and (2):
Y₂ ≧ Y₁ ≧ 2Y₃      (1)
and
T₂ ≧ T₁      (2)
wherein Y₁ , Y₂ and Y₃ are determined in accordance with JIS K 6734 (1975) at 100 ±2°C for 10 minutes.
