Photographic elements, diffusion transfer assemblages and processes are described which employ a nondiffusible, redox, dye-releasing compound comprising a ballasted, sulfonamidophenol or sulfonamidonaphthol compound having a dye moiety attached thereto through the sulfonamido group of the compound, the sulfonamido group being located in a position which is conjugated with respect to the position of the hydroxy group of the compound, and wherein (a) the compound has at least one substituent thereon in a position which is conjugated with respect to the position of the sulfonamido group, the substituent being selected from the group consisting of hydroxy, sulfonamido, phosphonamido and carbonamido, and (b) the compound not having a hydroxy, alkoxy, aryloxy, sulfonamido, phosphonamido or carbonamido group thereon in a position which is conjugated with respect to the position of the hydroxy group of the compound, with the proviso that when the compound is a 2-sulfonamidophenol and has only one substituent thereon in a position which is conjugated with respect to the position of the sulfonamido group, then that one substituent is located in the 5-position. These dye-releasers release the dye moiety at a faster rate than similar dye-releasers of the prior art.
