Abstract

Procedure for obtaining dispersed azo dyes, free of sulfonic acid groups, corresponding to the formula: **(See formula)** wherein A1 is an alkylene radical of at least two carbon atoms and may contain substituents; A2 is an alkylene radical of at least 4 carbon atoms that can contain substituents; R is a hydrogen atom or an optionally substituted alkyl or aryl radical; Y is hydrogen, alkyl, alkoxy, chlorine, bromine, aryloxy or cyclohexyloxy; Z is hydrogen, alkyl, alkoxy, chlorine, or bromine; and X is the residue of a diazo component of the aromatic series or of the heterocyclic series containing a nitrogen atom in the heterocyclic ring; characterized in that it comprises diazotizing an amine of formula X-NH2 and coupling the resulting diazo compound with a coupling component of formula: **(See formula)** the amine and the coupling component being free from sulfonic acid groups, and having A1, A2, R, X, Y and Z having the meanings given above.
