Abstract

Procedure for obtaining polyazoic dyes, which, in the form of free acid, respond to the general formula: ** (See formula) ** where Q is a sulfo-1,4-naphthylene radical; K is the remainder of a coupling component of the series hydroxynaphthalene, or aminonaphthalene, particularly a hydroxynaphthyl radical eventually substituted, with the hydroxy group in the ortho position relative to the azo bridge, especially a hydroxy-amino-sulfo-naphthyl radical; K1 is the residue of a coupling component, particularly of a coupling component of the hydroxybenzene, aminobenzene, hydroxynaphthalene or aminonaphthalene series; n and m are 0 or 1, where n + m = 0 or 2; characterized by comprising copulating tetrazotized azo dyes of the formula: ** (See formula) ** in which Q is defined as above, in an aqueous-alkaline medium, with 2 moles of a coupling component of the hydroxynaphthalene series, and in the case of the coupling component containing diazotizable amino groups, it is subsequently diazotized and coupled with 2 moles of a coupling component.
