Abstract

Procedure for obtaining dispersed azo dyes, free of additional sulfonic acid groups and carboxylic acid groups, corresponding to the formulas **(See formula)** where D is the residue of a diazo component of the aromatic or heterocyclic series; X is hydrogen, chlorine, bromine, alkyl, alkoxy, or acylamino; Y is hydrogen, chlorine, bromine, alkyl, or alkoxy; R1, R2, R3 and R4 independently represent hydrogen, methyl or ethyl; A is an alkylene radical of 1 to 6 carbon atoms; and Z is a hydrogen atom, or an optionally substituted alkyl radical, or a radical of the formula: **(See formula)** characterized in that it comprises diazotizing an amine of formula D-NH2 and coupling the resulting diazo compound with a coupling component of formula: **(See formula)** wherein D, X, Y, Z, A, R1, R2, R3 and R4 are defined as above, the amine and the coupling component being free of additional sulfonic acid groups and carboxylic acid groups.
