Abstract

The invention comprises dyes of formula <FORM:0951764/C3/1> where A may contain one or more alkyl or alkoxy groups of 1 to 3 carbon atoms and/or halogen atoms and/or acylamino groups, but not two methyl groups in the 2 and 4 positions. The dyes are made by conventional diazotisation and coupling processes. Coupling may be effected in substance or on the fibre or some other substratum. The dyes colour vegetable and regenerated cellulose fibres in yellow shades. Examples are provided of the preparation of the dyes and their use in dyeing cotton, representative of the coupling components used being acetoacetylaminobenzene and its 2.5-dimethoxy - 4 - chloro-, 2 - methyl-, 2 - methyl - 3 - chloro- and 2-methoxy-5-chloro-4-acetylaminobenzenes.
