摘要： Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a releasable 2-(2-heterocyclylazo)-1-naphthol dye moiety which contains a nitrogen atom adjacent to the point of attachment to the azo linkage. The compound contains 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.

摘要： Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a releasable azo dye moiety. The compound has the formula: ##STR1## wherein: G is a metal chelating group (or a salt or hydrolyzable precursor thereof) or a group which together with a ##STR2## IS CAR (bonded through the oxygen); G.sup.1 is a hydroxy group (or a salt of hydrolyzable precursor thereof);Z is an electron withdrawing group;Z' is alkyl, aryl or N(R).sub.2 (R being H, alkyl or aryl);Car is a ballasted carrier moiety; andT is 0 or 1.The dye can be transferred imagewise to an image-receiving layer where it can be contacted with metal ions to form a metal-complexed azo dye transfer image of excellent stability. The retained dye image in the photographic element can also be bleached, fixed and metallized to form a color transparency or a motion picture film.
