PHOTOGRAPHIC ELEMENTS CONTAINING NONDIFFUSIBLE 6-(2-THIENYLAZO)-3-PYRIDINOL CYAN DYE-RELEASING COMPOUNDS |
摘要 |
Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a releasable 6-(2-thienylazo)-3-pyridinol cyan dye moiety or precursor thereof, the compound containing: (a) in the 3-position of the thienylazo moiety a carboxy group, a salt thereof or a hydrolyzable precursor thereof; and (b) a ballasted carrier moiety which is capable of releasing the diffusible 6-(2-thienylazo)-3-pyridinol dye moiety or precursor thereof under alkaline conditions. |
