Abstract

Water-soluble monoazo dyestuffs are made by acylating a p water-soluble monoazo dyestuff containing at least one acylatable primary or secondary amino group with an arylcarboxylic acid halide sulphonic acid chloro- or bromoalkylamide having up to 4 carbon atoms in the alkylene group, or by coupling any aromatic diazo compound or the coupling component, the diazo compound or the coupling component or both containing at least one primary or secondary amino group acylated with such an arylcarboxylic acid halide. The invention also comprises water-soluble monoazo dyestuffs of the formula A-N=N-D containing up to two -NH,CO,Ar,SO2,X groups, where A is an aromatic radical which contains one benzene nucleus, D is an aromatic or heterocyclic radical of up to two benzene nuclei, Ar is an aromatic radical of up to two benzene nuclei and X is a chloro- or bromo-alkyl-amino radical containing up to 4 carbon atoms. The dyestuffs dye and print wool, natural silk linear polyamides and, in conjunction with an alkali and heat treatment, textile goods of natural and/or regenerated cellulose such as cotton in a variety of shades. Specification 823,098 also is referred to.
