ABSTRACT:
Water-soluble azo compounds, processes for their preparation and their use as dyestuffs.
Water-soluble azo compounds are described which have fiber-reactive properties and are suitable as dyestuffs for dyeing material, in particular fiber material, containing hydroxy and/or carboxamide groups, such as, for example, cellulosic fiber materials, such as those of cotton, wool or nylon, and which have, as the radical of a diazo component, a radical of the formula ##STR1## in which R is hydrogen, alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, halogen or sulfo, R.sup.o is hydrogen, alkyl having 1 to 4 carbon atoms, halogen, carboxy, aminocarbonyl, alkoxycarbonyl having 2 to 5 carbon atoms, sulfo or phenyl and R.sup.10 is hydrogen, alkyl having 1 to 4 carbon atoms or halogen, and which contain a fiber-reactive radical bonded to the coupling component via an amino group.
