Abstract

Water-soluble azo dyes having the formula: <IMAGE> wherein A represents the residue of a diazo component, R<1> represents alkyl or aryl, R<2> represents hydrogen or optionally substituted alkyl and R<3> represents hydrogen, halogen, alkyl, alkoxy, nitro, cyano or sulpho, the substituents being such that the dye molecule contains one or two sulphonic acid groups. The dyes are applicable as acid dyes to natural and synthetic polyamide textile materials on which they give yellow to red shades.
