Abstract, A dye-receiving element for thermal dye transfer process and assemblage comprises a compression layer between a film support and the dye image-receiving layer which has a greater compressibility than either the support or the receiving layer, is coated at a coverage of at least 2.0 g/m2, and has an elasticity of less than 500% elongation at break. In a preferred embodiment the, compression layer has a compression modulus of less than 350 mega Pascals. Use of the compression layer minimizes image defects while providing good scratch resistance.
