Abstract

Procedure for the production of diazo dyes, of general formula: **(See formula)** where E is the residue of an amino group containing a coupling component of the Benzene or naphthalanic series, the sulfonic acid group in ring A is in a meta or para position relative to the azo group and ring B can optionally be substituted by sulfonic acid and/or hydroxyl, said dye containing not more than 3 sulfonic acid groups, characterized in that it comprises a primary amine of the formula: **(See formula)** in which the sulfonic acid group is in a meta or para position with respect to the amino group, couple with aminonaphthalene of the formula: wherein ring B can optionally be substituted by sulfonic acid and/or hydroxyl and then diazotize the thus obtained aminomonoazo compound and couple with an amino group containing a coupling component of the benzene or naphthalene series.
