| titleOfInvention | Photographic products and processes employing novel nondiffusible pyridylazo(dialkylamino)phenol magenta dye-releasing compounds and precursors thereof |
| abstract | Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a releasable, pyridylazo(dialkylamino)phenol magenta dye moiety or precursor thereof, having the formula: <IMAGE> wherein: (a) R represents hydrogen, a hydrolyzable moiety, or may be taken together with the NHSO2 group to which it is attached to form CAR; (b) R1 represents hydrogen, a hydrolyzable moiety or CAR; (c) R2 and R3 each independently represents hydrogen, CAR, an alkyl group of 1 to about 6 carbon atoms, or they can be taken together with the nitrogen to which they are attached to form a 5- or 6-membered heterocyclic ring, or one of R2 and R3 can be an aryl group having from 6 to about 10 carbon atoms; and (d) CAR represents a ballasted carrier moiety capable of releasing the diffusible magenta dye moiety or precursor thereof under alkaline conditions; with the proviso that at least one of R, R1, R2 and R3 is CAR. |
