摘要

Azo dyes useful for dyeing or printing textile fibers or fabrics and containing novel aminobenzo heterocycles as diazo component have the formula where X is nitrogen or a radical of the formula CR6, where R6 is hydrogen, C1-C4-alkoxycarbonyl or C1-C6-alkanoyl, R1 and R2 are substituted or unsubstituted C1-C10-alkyl or substituted or unsubstituted C3-C4-alkenyl or additionally in the case of R1 hydrogen, R3 is hydrogen or C1-C4-alkoxy, R4 is C1-C6-alkyl, C1-C4-alkoxy, substituted or unsubstituted C1-C8-alkanoylamino, C1-C4-alkylsulfonylamino, C3-C4-alkenoylamino or substituted or unsubstituted C1-C4-alkoxycarbonylamino, and R5 is hydrogen, nitro, halogen, C1-C4-alkoxy, C1-C4-alkylthio or cyano.
