ABSTRACT:
A process for forming a dye image including the steps of: (a) exposing a photographic element comprising a light sensitive silver halide emulsion layer containing a color coupler compound capable of forming a heat transferable dye upon development; (b) developing the exposed element resulting from step (a) with a color developer solution to form a heat transferable dye image; (c) heating the exposed, developed element resulting from step (b) to thereby transfer the dye image from the emulsion layer to a dye receiving layer which is part of the photographic element or part of a separate dye receiving element brought into contact with the photographic element; and (d) separating the emulsion layer from the dye receiving layer containing the transferred dye image; wherein the color coupler compound is of the following formula (I):
