PHOTOGRAPHIC PRODUCTS AND PROCESSES EMPLOYING NOVEL NONDIFFUSIBLE 6-ARYLAZO-3-PYRIDINOL MAGENTA DYE- RELEASING COMPOUNDS AND PRECURSORS THEREOF |
摘要 |
<p>Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a releasable 6-arylazo-3-pyridinol magenta dye moiety or precursor thereof having the formula: wherein: (a) R represents hydroxy or amino; (b) R1 represents hydrogen, a hydrolyzable moiety or CAR; (c) G represents carboxy; a hydrolyzable ester or a sulfamoyl group; (d) CAR represents a ballasted carrier moiety capable of releasing the diffusible 6-arylazo-3-pyridinol dye moiety or precursor thereof under alkaline conditions; and (e) n is 0, 1 or 2, with the proviso that when n is 0, then R1 is CAR.</p> |
