Water-soluble azo compounds are described which have fiber-reactive properties and are suitable as dyes for dyeing material containing hydroxyl and / or carbonamide groups, in particular fiber material, such as, for example, cellulose fiber materials, such as those made of cotton, wool and nylon, and which are the residue of a diazo component a radical of the general formula have in which R is hydrogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, halogen or sulfo and G forms the remainder of the benzene ring of a heterocycle free of olefinic double bonds which has at least one carbonamide group of the formula - CO-N (R 10 ) - in which R 10 contains hydrogen, alkyl of 1 to 4 carbon atoms or 1 to 3 substituents from the group sulfo, carboxy, alkoxy of 1 to 4 carbon atoms, alkyl of 1 to 4 carbon atoms, halogen, cyano, nitro and amino-substituted aryl of 6 to 10 carbon atoms, and optionally 1 or 2 further hetero groups from the series -O-, -S- and -N (R 10 ) - with R 10 has the meaning given and which contain a fiber-reactive radical bonded to the coupling component via an amino group. |
