ABSTRACT:
Azo dyes of the formula in which X.sub.1 and X.sub.2 independently of one another are alkyl, cycloalkyl, alkenyl, aryl or aralkyl, Y.sub.1 is hydrogen or alkyl, Y.sub.2 is hydrogen, alkyl, alkenyl or aryl or together with Y.sub.1 stands for the atoms required to complete a ring, Z.sub.1 is hydrogen, alkyl, alkenyl, alkoxy, aryl, aryloxy, alkylmercapto, arylmercapto, halogen, cyano, carbalkoxy or stands for the atoms which together with Y.sub.1 form a ring, and D.sub.1 is the radical of a heterocyclic azo component such as a thienyl, thiazolyl, benzthiazolyl, pyrazolyl or imidazolyl radical, or is phenyl optionally substituted by alkyl, cycloalkyl, alkoxy, alkenyl, electronegative substituents such as halogen, cyano, nitro or carboxylic acid, alkyl- or phenylsulfone or N-alkyl or N,N-dialkyl-substituted sulfonamido, can be used as image dyes in photographic silver dye-bleach materials, or for dyeing textile materials.
