Photographic products and processes employing novel dye developer compounds

摘要

Photographic elements, diffusion transfer assemblages and processes are described which employ a novel dye developer compound having a dye moiety such as an arylazopyrazolotriazole. The compound contains: (a) a nitrogen atom in a metal chelating location in at least one of the rings attached to the azo group; (b) in the ortho position of the arylazo moiety a metal chelating group (or a salt thereof or a hydrolyzable precursor thereof), and (c) a silver halide developer moiety.
