ABSTRACT:
Azo compounds of the formula D.sup.o --N.dbd.N--K.sup.o, in which D.sup.o is a radical of the formula (2), (2a) or (2b) ##STR1## in which Y is a substituent which can be eliminated by alkali to form the vinyl group, X is chlorine or bromine and R is hydrogen, lower alkyl, phenyl or halogen, and K.sup.o is the radical of a coupling component or another radical which contains azo groups, K.sup.o containing a group of the formula --N(R.sup.o)--Z, in which R.sup.o is hydrogen or lower alkyl and Z is a radical of the formula ##STR2## in which A is halogen or cyanoamido, R.sup.20 is hydrogen or lower alkyl, and R.sup.21 has one of the meanings given for R.sup.20, or is an optionally methyl-substituted cycloalkylene radical, or is a phenyl radical, or in which R.sup.20 and R.sup.21, together with the nitrogen atom and if appropriate one or two further hetero groups, can form a 5- or 6-membered heterocyclic radical.
The azo compounds are suitable as fiber-reactive dyestuffs for dyeing material containing hydroxy and/or carboxamide groups, such as cellulose fibers, wool and synthetic polyamide fibers.
