Nondiffusible compounds are described having at least one releasable 2-(2-heterocyclylazo)-1-naphthol dye moiety having the formula: ##STR1## wherein: G is hydroxy, a salt thereof, or a hydrolyzable precursor thereof; or a group which together with ##STR2## is CAR, said CAR being bonded to the naphthalene group through the oxygen of said ##STR3## group; Z represents the atoms necessary to complete a heterocyclic ring; CAR represents a ballasted carrier moiety; and t is a positive integer of 1 to 2.
本文描述了至少具有一个可释放的2-(2-杂环偶氮基)-1-萘酚染料基团的不可扩散化合物,其分子式为:##STR1##
其中:G代表羟基,其盐或其可水解前体;或是与##STR2##一起形成CAR的基团,所述CAR通过##STR3##基团的氧原子与萘基结合;Z代表完成杂环环所需的原子;CAR代表负载载体基团;t为1至2的正整数。
