Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
122 words
A process for forming a color image comprising: (a) forming a thermal dye transfer image in a polymeric dye image-receiving layer of an intermediate dye-receiving element comprising a metallic surface having thereon said dye image-receiving layer by imagewise-heating a dye-donor element and transferring a dye image to the dye image-receiving layer, (b) transferring the polymeric dye image-receiving layer to the surface of a final receiver element by adhering the dye image-receiving layer to the final receiver element, and (c) stripping the metallic surface from the dye image-receiving layer, wherein the intermediate dye receiving element further comprises a stripping layer between the metallic surface and the dye image-receiving layer, said stripping layer comprising a mixture of a hydrophilic cellulosic material and a polyethyleneglycol.
Claim 2
Dependent Claim
122 words
A process for forming a color image comprising: (a) forming a thermal dye transfer image in a polymeric dye image-receiving layer of an intermediate dye-receiving element comprising a metallic surface having thereon said dye image-receiving layer by imagewise-heating a dye-donor element and transferring a dye image to the dye image-receiving layer, (b) transferring the polymeric dye image-receiving layer to the surface of a final receiver element by adhering the dye image-receiving layer to the final receiver element, and (c) stripping the metallic surface from the dye image-receiving layer, wherein the intermediate dye receiving element further comprises a stripping layer between the metallic surface and the dye image-receiving layer, said stripping layer comprising a mixture of a hydrophilic cellulosic material and a polyethyleneglycol.
Claim 3
Dependent Claim
21 words
