Compounds of the general formula I <IMAGE> I where D is the radical of a diazo component, R is hydrogen, hydroxy or unsubstituted or substituted alkyl, alkenyl, cycloalkyl, aralkyl, phenyl or heterocyclic ring, R1 and R2 independently of one another are hydrogen or unsubstituted or substituted alkyl, alkenyl, alkynyl, cycloalkyl, aralkyl or aryl, or R1 and R2 together with the nitrogen are a saturated heterocyclic 5-membered to 7-membered ring, X is hydrogen, chlorine, bromine, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, allyloxy, beta -cyanoethoxy, benzyloxy, phenoxy, beta -alkoxycarbonylethoxy, where alkoxy is of 1 to 4 carbon atoms, alkylmercapto of 1 to 4 carbon atoms, phenylmercapto or alkanoylamino of 1 to 4 carbon atoms, and Y is chlorine, alkyl of 1 to 4 carbon atoms, allyloxy, alkoxy of 1 to 4 carbon atoms or beta -cyanoethoxy, or X and Y together are a fused benzene ring which is unsubstituted or substituted by alkyl alkoxy chlorine or bromine. The compounds are in particular suitable for dyeing cotton and union fabrics of cotton and synthetic fibers, preferably polyesters. The dyeings obtained are, in part, very fast.
