Abstract

The invention comprises water-insoluble monoazo dyes of the formula <FORM:0992146/C4-C5/1> in which X represents a methyl or carbethoxy group, Y represents an alkyl group having from 1-5 carbon atoms or a benzene residue which may be substituted by a methyl group or chlorine atom and in which the benzene nuclei A and B may contain substituents other than sulphonic and carboxylic acid groups. Examples are furnished. The dyes yield yellow dyeings or polyester fibres.
