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.
描述了使用一种新型的不可扩散化合物的摄影元素、扩散转移组合物和过程,该化合物具有可释放的6-(2-噻吩基偶氮)-3-吡啶酚青色染料基团或其前体,该化合物包含:(a) 在噻吩基偶氮基团的3位上的羧基、其盐或可水解前体;以及(b) 能够在碱性条件下释放可扩散的6-(2-噻吩基偶氮)-3-吡啶酚染料基团或其前体的配基载体基团。
