Abstract

Abstract Fiber-reactive azo dyestuffs are obtained by diazotizng an amine of the formula ##STR1## in which Z stands for --CH.sub.2 --CH.sub.2 --A or --CH═CH.sub.2 in which A is N,N-dialkylamino with 1 to 4 carbon atoms in each alkyl moiety or is the radical of a mono- or poly-basic acid capable of being split off by an alkaline agent and coupling it with an azo component of the formula H-B, in which B is aniline, naphthol, naphthylamine, aminonaphthol, pyridone, aminopyridine, 1-phenyl-4-aminopyrazole or 1-phenyl-5-pyrazolone, unsubstituted or substituted on the aromatic and/or heterocyclic moieties by one to four groups selected from alkyl, alkoxy, oxalkyl, cyanoalkyl, aminoalkyl or alkoxyalkyl with 1 to 6 carbon atoms in each alkyl and alkoxy moiety, chlorine and bromine, sulfonic acid, vinylsulfonyl, carboxyl, acylamino and arylamino groups.
