Abstract
A process for forming a color proofing image by thermal transfer systems and an improved thermal transfer receptor sheet are described. The receptor sheet has a hot melt adhesive layer with one quarter percent or less of particles therein. In the thermal transfer process, both the image and a thermal transfer receptor layer are transferred to a second receptor surface.
