Abstract
Procedure for the preparation of azo dyes lacking acidic solubilizing groups, and corresponding to the formula ** (See formula) ** in which R1 is an optionally substituted alkyl, cycloalkyl, aralkyl, aryl or heterocyclic radical; Z1 is a radical of the formula = NH or -NH2; Z2 is a radical of the formulas = NR2, -NHR2, -NH3R4, -OR5 or -SR6, where R2, R3 and R4 are each hydrogen atoms or alkyl, aralkyl, cycloalkyl, aryl or hethocyclic radicals, optionally substituted, R3 and R4, together with the nitrogen atom attached to them, can form a pentagonal or hexagonal ring, R5 is a hydrogen atom or an optionally substituted alkyl, aralkyl, cycloalkyl, aryl or heterocyclic radical, R6 is a hydrogen atom or an optionally substituted alkyl, aralkyl, cycloalkyl, aryl or heterocyclic radical; Z3 is a radical of the formulas = NR1 or -NHR1; Y is a radical of the formulas -CONH2 or -CN; D is the radical of an aromatic or heterocyclic diazo compound; and the dihydropyridine ring A is only replaced by a nitrogen atom linked two voices and contains two double bonds, characterized by coupling the diazo compound of an amine of the formula D-NH2 with a coupling component of the formula ** (See formula) ** and eventually, when Y equals CN, convert the cyano group in the -CONH2 group to concentrated sulfuric acid.
