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
wherein X is
Z is H, alkyl or aryl; R is H, alkyl or aryl; DYE is any dye moiety; R, is H, alkyl, aryl, -NH2. -NHR2. -N(R2)2 or -OR2; R2 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.
