Abstract
A thermal dye transfer process, and intermediate receiver used therein, for obtaining a color image which is used to represent a printed color image obtained from a printing press comprising (a) imagewise-heating by means of a laser a dye-donor element in contact with a polymeric dye image-receiving layer of an intermediate dye-receiving element, thereby transferring a dye image to the dye image-receiving layer, the intermediate dye-receiving element comprising the dye image-receiving layer and a layer substantially opaque to light at the wavelength the laser is operated at, (b) adhering the dyed polymeric dye image-receiving layer to a final receiver element, and (c) separating the opaque layer from the dyed image-receiving layer. Preferably, the opaque layer is reflective, and most preferably specularly reflective.
