摘要：
Azo dyes useful for dyeing or printing textile fibers or fabrics and containing novel aminobenzo heterocycles as diazo component have the formula ##STR1## where X is nitrogen or a radical of the formula CR.sup.6, where R.sup.6 is hydrogen, C.sub.1 -C.sub.4 -alkoxycarbonyl or C.sub.1 -C.sub.6 -alkanoyl,R.sup.1 and R.sup.2 are substituted or unsubstituted C.sub.1 -C.sub.10 -alkyl or substituted or unsubstituted C.sub.3 -C.sub.4 -alkenyl or additionally in the case of R.sup.1 hydrogen,R.sup.3 is hydrogen or C.sub.1 -C.sub.4 -alkoxy,R.sup.4 is C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.4 -alkoxy, substituted or unsubstituted C.sub.1 -C.sub.8 -alkanoylamino, C.sub.1 -C.sub.4 -alkylsulfonylamino, C.sub.3 -C.sub.4 -alkenoylamino or substituted or unsubstituted C.sub.1 -C.sub.4 -alkoxycarbonylamino, andR.sup.5 is hydrogen, nitro, halogen, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -alkylthio or cyano.
