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/m.sup.2, 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.
Claims20
A dye image-receiving element for thermal dye transfer comprising a plastic film support having thereon, in order, a compression layer and a dye image-receiving layer, said compression layer having a compressibility greater than that of the support or the dye image-receiving layer, said compression layer being coated at a coverage of at least 2.0 g/m.sup.2, and said compression layer having an elasticity of less than 500% elongation at break.
In a process of forming a dye transfer image comprising imagewise-heating a dye-donor element and transferring to dye image to a dye-receiving element to form said dye transfer image, said dye-receiving element comprising a plastic film support having thereon a dye image-receiving layer, the improvement wherein a compression layer is located between said support and said dye image-receiving layer, said compression layer having a compressibility greater than that of said support or said dye image-receiving layer, said compression layer being coated at a coverage of at least 2.0 g/m.sup.2, and said compression layer having an elasticity of less than 500% elongation at break.
In a thermal dye transfer assemblage comprising:
- (a) a dye-donor element comprising a support having thereon a dye layer, and
- (b) a dye-receiving element comprising a plastic film support having thereon a dye image-receiving layer,
- said dye-receiving element being in a superposed relationship with said dye-donor element so that said dye layer is in contact with said dye image-receiving layer,
- the improvement wherein a compression layer is located between said support of said dye-receiving element and said dye image-receiving layer, said compression layer having a compressibility greater than that of said support or said dye image-receiving layer, said compression layer being coated at a coverage of at least 2.0 g/m.sup.2, and said compression layer having an elasticity of less than 500% elongation at break.
