Abstract
A process for forming a color image which may be used to represent a printed color image to be obtained from a printing press comprising (a) forming a thermal dye transfer image in a polymeric dye image-receiving layer of an intermediate dye-receiving element by imagewise-heating a dye-donor element and transferring a dye image to the dye image-receiving layer, (b) applying a dye-migration barrier layer to one surface of a paper substrate, and (c) transferring the imaged polymeric dye image-receiving layer to the surface of the paper having the dye-migration barrier layer applied thereon. By first applying a dye-migration barrier layer to the paper substrate, dye smear and spreading due to migration of dye into the paper can be eliminated and a high quality final color image can be obtained.
