ABSTRACT:
Diffusion transfer color processes and products are disclosed employing image-dye providing materials providing magenta image dyes having the chromophoric system represented by the formula ##STR1## wherein each R is the same or different and is an alkyl group, and each X is the same or different and is hydrogen or an alkyl group (including substituted alkyl). The dye image-providing material includes a diffusion control moiety, such as a hydroquinonyl group, and may be diffusible or nondiffusible as a function of the diffusion control moiety.
