    • Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a releasable, bridged, azoaminophenol magenta dye moiety or precursor thereof having the formula: ##STR1## wherein: (a) R represents hydrogen, a hydrolyzable moiety or CAR;(b) R.sup.1 represents hydrogen;(c) R.sup.2 represents an alkyl group of 1 to about 6 carbon atoms or CAR; or R.sup.1 and R.sup.2 represent an alkylene group which can be taken together with the atoms to which they are attached to complete a 5- or 6-membered heterocyclic ring;(d) R.sup.3 represents an alkyl group of 1 to about 6 carbon atoms or CAR;(e) R.sup.4 represents hydrogen; or R.sup.3 and R.sup.4 represent an alkylene group which can be taken together with the atoms to which they are attached to complete a 5- or 6-membered heterocyclic ring;with the proviso that at least one of the 5- or 6-membered heterocyclic rings of (c) or (e) is present in the compound;(f) CAR represents a ballasted carrier moiety capable of releasing the diffusible magenta dye moiety or precursor thereof under alkaline conditions; and(g) n is 0, 1 or 2, with the proviso that when n is 0, then at least one of R, R.sup.2 or R.sup.3 is CAR.
    • 描述了摄影元件,扩散转移组合和方法,其使用具有下列通式的可释放的,桥联的偶氮氨基苯酚品红色染料部分或其前体的新型不扩散化合物:其中:(a)R表示氢,可水解部分或CAR ; (b)R1表示氢; (c)R 2表示1〜6个碳原子的烷基或CAR; 或R 1和R 2表示可以与它们连接的原子一起形成的亚烷基,以完成5-或6-元杂环; (d)R 3表示1〜6个碳原子的烷基或CAR; (e)R4代表氢; 或R 3和R 4表示可以与它们连接的原子一起形成的亚烷基,以形成5-或6-元杂环; 条件是(c)或(e)的5-或6-元杂环中的至少一个存在于化合物中; (f)CAR表示在碱性条件下能够释放可扩散品红染料部分或其前体的压载载体部分; 和(g)n为0,1或2,条件是当n为0时,R,R 2或R 3中的至少一个为CAR。
