Abstract

Water-soluble monoazo dyes having the formula: <IMAGE> wherein A represents the residue of a diazo component of the benzene or naphthalene series, and R represents an optionally substituted alkyl, aralkyl or acyl radical, the substituents being such that the dye molecule contains one or two acidic water-solubilising groups and the -OR 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.
