ABSTRACT OF THE DISCLOSURE Photographic elements, diffusion transfer assem- blages and processes are described which employ a novel nondiffusible compound having a releasable azo dye moiety. The compound has the formula: Image wherein: G is a metal chelating group (or a salt or hydro- lyzable precursor thereof) or a group which together with a C " -C-O group is CAR. (bonded through the oxygen); G1 is a hydroxy group (or a salt or hydrolyzable precursor thereof); Z is an electron withdrawing group; Z is alkyl, aryl or N(R)2 (R being H, alkyl or aryl); CAR is a ballasted carrier moiety; and t is O 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.
