ABSTRACT:
Diffusion transfer photographic color processes and products are described utilizing novel image dye-providing materials which provide image dyes having the chromophoric system represented by the formula ##STR1## wherein X is ##STR2## or --SO.sub.2 --R.sub.1 ; Z is H, alkyl or aryl; R is H, alkyl or aryl; DYE is any dye moiety; R.sub.1 is H, alkyl, aryl, --NH.sub.2, --NHR.sub.2, --N(R.sub.2).sub.2 or --OR.sub.2 ; R.sub.2 is H, alkyl or aryl; and m is 1 or 2. The image dye providing material includes a diffusion control moiety such as a hydroquinonyl group or a precursor thereof and may be diffusible or nondiffusible as a function of the diffusion control moiety.
