    • A Photographic recording material is described which employs a novel, nondiffusible compound capable of releasing at least one diffusible cyan dye moiety comprising a 6-heterocyclylazo-3-pyridinol compound having the structural formula:
      wherein:

      (a) Y represents the atoms necessary to complete a 5-or 6-membered aromatic heterocyclic fused ring;
      (b) CAR represents a ballasted carrier moiety capable of releasing the diffusible cyan dye moiety as a function of development of a silver halide emulsion layer under alkaline conditions,
      (c) R represents a hydroxy group, a salt thereof, or a hydrolyzable precursor thereof, or CAR which is linked to the dye moiety through an oxygen atom thereon; and
      (d) n is 0, 1 or 2, with the proviso that when n is 0, then R is CAR which is linked to the dye moiety through an oxygen atom thereon.
    • 照相记录材料进行说明,其采用新颖的,非扩散化合物能够释放至少一种扩散性青色染料部分,其包含具有下列结构式的6- heterocyclylazo -3-吡啶酚化合物的: worin:(1)Y darstellt原子 要完成的5-或6-元芳族杂环稠环; (B)CAR darstellt能够释放扩散性青色染料部分作为在碱性条件下的卤化银乳剂层的显影的函数的一个镇流载体部分,(C)R darstellt羟基,其盐,或它们的可水解的前体 或CAR所有这一切是通过在其上的氧原子连接于染料的部分; 和(d)n为0,1或2,其条件没有当n是0,R是CAR所有这一切都被链接到染料部分通过氧原子,然后在其上。
