Abstract

Procedure for obtaining azo dyes, free of sulfonic acid groups and other carboxylic acid groups, of formula: ** (See formula) ** wherein A represents an optionally substituted aryl radical free of a carboalkoxy group in an ortho position with respect to the azo bond, or an optionally substituted nitrogenous heterocyclic radical; X represents hydrogen, alkyl, chloro, bramo or alkoxy; R1 represents a hydrogen atom or an optionally substituted alkyl radical, R2 represents an acyl group or R1 and R2 together form with the nitrogen atom a 5- or 6-membered nitrogen heterocyclic ring, having two -CO- groups attached to the atom of nitrogen; R represents a hydrogen atom or an optionally substituted alkyl, cycloalkyl, aryl or heterocyclic radical, or a group of formula -YQ; Y is an optionally substituted alkylene radical and Q is a group -OCOZCOOH or -NR3COZCOOH where R3 represents hydrogen or alkyl and Z represents a direct bond or an alkylene or arylene radical; characterized in that it comprises diazotizing an amine of the formula: - A1 -NH2 and coupling the resulting diazo compound with a coupling component of the formula: ** (See formula) ** wherein R, R1, R2, Q, X and Y are defined as above and A1 represents an optionally substituted aryl radical free of a carboalkoxy group in an ortho position with respect to the amino group, or an optionally substituted nitrogenous heterocyclic radical, being free the amine and the coupling component of sulfonic acid groups and other carboxylic acid groups.
