ABSTRACT:
Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a releasable 6-arylazo-2-amino-3-pyridinol dye moiety or precursor thereof. The compound contains in the ortho position of the arylazo moiety a ballasted carrier moiety attached thereto either through a sulfonamido linking group or through the oxygen of a ##STR1## which said ballasted carrier moiety contains, the ballasted carrier moiety being capable of releasing the diffusible 6-arylazo-2-amino-3-pyridinol dye or precursor thereof 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 6-arylazo-2-amino-3-pyridinol dye transfer image of excellent stability.
