Abstract of the Disclosure Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a releasable, bridged, azoaminophenol magenta dye moiety or precur- sor thereof having the formula: Image wherein: (a) R represents hydrogen, a hydrolyzable moiety or CAR; (b) R2 represents hydrogen; (c) R2 represents an alkyl group of 1 to about 6 carbon atoms or CAR; or R1 and R2 represent an alkylene group which can be taken together with the atoms to which they are attached to complete a 5- or 6-membered heterocyclic ring; (d) R3 represents an alkyl group of 1 to about 6 carbon atoms or CAR; (e) R4 represents hydrogen; or R3 and R6 represent an alkylene group which can be taken with the atoms to which they are attached to complete a 5- or 6-membered heterocyclic ring; with the proviso that at least one of the 5- 6- membered heterocyclic ring of (c) or (e) is present in the compound; (f) CAR represents a ballasted carrier moiety capable of releasing the diffusible magenta dye moiety or precursor thereof under alkaline conditions; and (g) n is 0, 1 or 2, with the proviso that when n is 0, then at least one of R, R2 or R3 is CAR.
