ABSTRACT:
This invention relates to color proofing, or more particularly to an improved photographic element and transfer method of color proofing wherein a colored image is prepared by successively producing images of different colors from distinct color separation films onto a single receptor sheet. The photographic element has a support having a release surface, a colored photosensitive layer on the release surface and an adhesive layer on the colored layer. The adhesive layer comprises a thermally activated adhesive which is preferably a plasticizer in admixture with at least one copolymer selected from the group consisting of copolymers of methyl methacrylate and ethyl acrylate and copolymers of acrylic acid and acrylic esters having an acid number of from about 80 to about 100.
