Organic compounds for use in a dye diffusion transfer process and photographic elements incorporating them

A ballasted non-diffusing compound that is capable of releasing a diffusible particularly light-fast azo dye from a carrier moiety, characterized in that said compound corresponds to the following general formula: CAR-L-G-D wherein: CAR represents a ballasted carrier moiety making said compound non-diffusing in a hydrophilic colloid medium under wet alkaline conditions, L represents a chemical group cleavable or releasable from the carrier moiety as a function of a redox-reaction or argentolytic reaction taking place in the development of a silver halide emulsion layer under alkaline conditions; G represents a bivalent organic group containing at least one aromatic nucleus being substituted with a R5R6NSO2NH-group, wherein R5 and R6 (same or different) represent hydrogen, an alkyl group including a substituted alkyl group or an aryl group including a substituted aryl group, and D is an azo dye part chemically linked to an aromatic nucleus of G.
