Abstract

Procedure for the preparation of new diazotable dyes on the fiber, included in the general formula **(See formula)** in which A and B, different from each other, represent amino-naphtholsulfonic acids chosen from the group consisting of: 1-amino-8-naphthol-3,6-disulfonic acid, 1-amino-8-naphthol-4,6-disulfonic acid, 2-amino-8-naphthol-6-sulfonic acid and 2-amino-5-naphthol-7-sulfonic acid, characterized by coupling, in a single phase and in an alkaline medium, 1 mole of a tetraazo derivative of 4,4-diamino-azobenzole with a composition that participates in equimolar proportions of coupler A and coupler B whose meaning has been described above.
