Abstract

Procedure for obtaining the polyazoic dyes of the formula ** (See formula) ** where: n is chosen between 1 and 2; R'is chosen from hydrogen, halogen and optionally substituted alkyl and alkoxy residues; Y is chosen from hydrogen and the sulfonic acid group; R is the remainder of a diphenylaminosulfonic acid; and R1 is selected from an unsubstituted phenyl residue, a phenyl residue substituted by halogen, nitro, hydroxyl, cyano, carboxyl, -SO3H, trifluor- and trichloroalkyl, alkyl and alkoxy substituted if appropriate, and a naphthyl residue optionally substituted, characterized in that 2 moles of a diazotized aminophenylaminosulfonic acid of the formula: R - NH2 (II) and 1 mole of a diazotized amine of formula R1 - NH2 (III) are coupled with 1 mole of a coupling component of the formula (see formula) (Machine-translation by Google Translate, not legally binding)
