ORGANIC COMPOUNDS FOR USE IN A DYE DIFFUSION TRANSFER PROCESS AND PHOTOGRAPHIC ELEMENTS INCORPORATING THEM

摘要

A ballasted non-diffusing compound that is capable of releasing a diffusible particularly light-fast azo dye from a non-diffusible carrier moiety, wherein said compound contains not more than two aromatic nuclei between said carrier moiety and a dye part that remaining linked to said aromatic nuclei is releasable by redox-reaction and wherein at least one of said aromatic nuclei is substituted with a R4SO2NH- group as defined.
