    Abstract: 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## group is CAR (bonded through the oxygen); G.sup.1 is a hydroxy group (or a salt or 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.

    Abstract: Compounds of the formula ##STR1## in which R.sub.1 signifies a group of the formula --NH.sub.2, --NH--R.sub.4 or --O--R.sub.4, in which R.sub.4 signifies a (C.sub.1-8)alkyl radical, a (C.sub.5-8)cycloalkyl radical or an unsubstituted or substituted phenyl, naphthyl or heterocyclic radical,Each of R.sub.2 and R.sub.3, which may be the same or different, signifies a hydrogen atom, a hydroxyl, (C.sub.1-8)alkoxy, amino, (C.sub.5-8)cycloalkylamino, (C.sub.1-8)alkylamino, (C.sub.1:8)dialkylamino, phenyl- or naphthylamino or N-phenyl-N-(C.sub.1-8)alkylamino group,A signifies a nitrogen atom or a group of the formula ##STR2## in which R.sub.6 signifies a hydrogen or halogen atom or a (C.sub.1-8)alkyl radical,Either n is 1 and D signifies the radical of a diazo component,Or n is 2 and D signifies the radical of a tetrazo component,Are useful as coloring materials, especially as pigments for plastics, synthetic resins, varnishes, viscose, cellulose acetate, printing inks and paper stock. The dyeings exhibit good fastness to heat, light, weather and solvents and resistance to migration, crystallization and chemicals such as sulfur dioxide and alkalis. The compounds wherein R.sub.2 and R.sub.3 are other than hydroxy are also useful as disperse dyes for high molecular weight hydrophobic substrates such as polyesters, cellulose acetates and synthetic polyamides. These dyeings exhibit good fastness to light, sublimation, washing, solvents, rubbing, gas fumes, reduction and chlorine.
