Photographic products and processes employing nondiffusible 1-arylazo-4-isoquinolinol dye-releasing compounds

摘要

Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a releasable 1-arylazo-4-isoquinolinol dye moiety. The compound contains: (a) in the ortho position of the arylazo moiety a metal chelating group, a salt thereof or a hydrolyzable precursor thereof; and (b) a ballasted carrier moiety which is capable of releasing the diffusible azo dye under alkaline conditions. The dye is transferred imagewise to an image-receiving layer where it is contacted with metal ions to form a metal-complexed azo dye transfer image of excellent stability.
