Abstract

A method of manufacturing an acid dye for natural and synthetic polyamide fibers and for secondary cellulose acetate fibers, having the structure **(See formula)** where AN = N- is the subsequent coupling moiety of a diazotized aromatic amine, a diazotized heterocyclic amine or a diazotized amine monoazo intermediate, R is an aryl radical having one or two aromatic rings, the moiety being attached to it after coupling AN = N- through the ring carbon in the para- position relative to the nitrogen atom; R1 is a radical attached to the nitrogen atom through an alcoholic carbon and M is -H, -Na, -K or -NH4, the method of which comprises diazotizing an aromatic amine, a heterocyclic amine or an intermediate compound; amine monoazoic; coupling the diazo compound to form a compound having the structure **(See formula)** where D is a hydrogen atom attached to the ring carbon of R, which is located in a para position with respect to the nitrogen atom, and recover the dye in the desired salt form.
