Abstract

Water-soluble monoazo dyes which, in the form of the free acids, have the formula: <IMAGE> wherein A represents the residue of a diazo component, ring B may carry further substituents and X denotes the atoms required to form a 5- or 6- membered saturated heterocyclic ring. The dyes are applicable as acid dyes to natural and synthetic polyamide textile materials on which they give orange to red shades.
