Abstract

Water-soluble disazo dyes having the formula: <IMAGE> wherein A represents the residue of a diazo component of the benzene or naphthalene series; M represents an optionally substituted 1,4-phenylene or 1,4- naphthylene radical; R<1> represents optionally substituted alkyl, aralkyl or acyl; and R<2> represents hydrogen or -SO3H, the substituents being such that the dye molecule contains one or two acidic water-solubilising groups and the -OR<1> group being in the ortho or para position relative to the azo group. The dyes are applicable as acid dyes to natural and synthetic polyamide textiles.
