Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a releasable azo dye moiety. The compound has the formula: ##STR1## wherein: G is a metal chelating group (or a salt or hydrolyzable precursor thereof) or a group which together with a ##STR2## is CAR (bonded through the oxygen); G.sup.1 is a hydroxy group (or a salt or hydrolyzable precursor thereof); Z is an electron withdrawing group; Z' is alkyl, aryl or N(R).sub.2 (R being H, alkyl or aryl); CAR is a ballasted carrier moiety; and t is 0 or 1. The dye can be transferred imagewise to an image-receiving layer where it can be contacted with metal ions to form a metal-complexed azo dye transfer image of excellent stability. The retained dye image in the photographic element can also be bleached, fixed and metallized to form a color transparency or a motion picture film.
描述了使用一种新颖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偶氮染料基团。该化合物的化学式为:其中:G是金属螯合基团(或其盐或可水解前体)或与CAR(通过氧键结合)的一组;G.sup.1是羟基(或其盐或可水解前体);Z是一个电子吸引基团;Z'是烷基、芳基或N(R).sub.2(R为H、烷基或芳基);CAR是一个配重载体基团;t为0或1。染料可以以图像方式转移至图像接收层,在那里它可以与金属离子接触,形成优异稳定性的金属络合偶氮染料转移图像。摄影元素中保留的染料图像也可以被漂白、固定和金属化,形成彩色透明片或电影胶片。
