Abstract

Procedure for obtaining polyazoic dyes of the formula **(See formula)** wherein D represents the residue of an aromatic-carbocyclic or aromatic-heterocyclic diazo component, X represents hydrogen or a substituent, Y represents OH, NH2, Ar represents an arylene residue, preferably a phenylene or naphthylene residue, optionally substituted, K stands for a monosulfonaphthalene residue, the hydroxy group being in the position or with respect to the azo group, Z for a substituent, preferably an optionally substituted amino group or an arylazo group, n represents 1 or 2; characterized by diazotized amines of the formula D-NH2 in which D has the meaning indicated above, they are coupled, in a weakly acidic or alkaline medium, with aminoarylene pyrazoles of the formula **(See formula)** in which X, Y and Ar have the meaning indicated above, the aminoazo dyes obtained are still diazotized and coupled with coupling components of the formula **(See formula)** in which K, Z and n have the meanings indicated above, in an alkaline, aqueous, aqueous-organic or organic medium.
