Water-soluble azo compounds, containing a diazo component with a heterocyclic moiety, and a coupling component with a fibre-reactive group, suitable as dyestuffs

摘要

Water-soluble azo compounds are described which possess fiber- reactive properties and which are suitable as dyes for the dyeing of material, in particular fiber material, which contains hydroxy and/or carboxamido groups, examples being cellulosic fiber materials such as cotton, wool and nylon, and which compounds possess, as the radical of a diazo component, a radical of the formula ##STR1## 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 to the benzene ring the radical of a heterocycle which is free from olefinic double bonds and which contains at least one carboxamide group of the formula --CO--N(R.sup.10)-- in which R.sup.10 is hydrogen, alkyl of 1 to 4 carbon atoms or aryl of 6 to 10 carbon atoms which maybe substituted by from 1 to 3 substituents from the group consisting of sulfo, carboxy, alkoxy of 1 to 4 carbon atoms, alkyl of 1 to 4 carbon atoms, halogen, cyano, nitro and amino, and which if desired possesses 1 or 2 further hetero-groups from the series consisting of --O-- , --S-- and --N(R.sup.10)-- where R.sup.10 is as defined, and which compounds contain a fiber-reactive radical which is attached to the coupling component by an amino group.
