Photographic products and processes employing novel nondiffusible heterocyclyazonaphthol dye-releasing compounds |
摘要 |
Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a releasable 2-(2-heterocyclylazo)-1-naphthol dye moiety which contains a nitrogen atom adjacent to the point of attachment to the azo linkage. The compound contains a ballasted carrier moiety which is capable of releasing the diffusible azo dye under alkaline conditions. The dye is transferred imagewise to an image-receiving layer where it is contacted with metal ions to form a metal-complexed azo dye transfer image of excellent stability.
