Abstract
Procedure for obtaining water-insoluble azo dyes, of general formula: **(See formula)** in which R means an aromatic or heterocyclic residue, free of acidic groups that make them soluble in water; X stands for hydrogen, an optionally branched and/or substituted alkyl group, a cycloalkyl, aralkyl, aryl or heteroaryl group, optionally substituted; Y stands for hydrogen, an alkyl or alkenyl group, optionally branched and/or substituted, a cycloalkyl, aralkyl, aryl or hetaryl group, optionally substituted, also a moiety of formula (see formula), where R1 and R2 signify hydrogen, an alkyl group, optionally branched, a cycloalkyl, aralkyl or aryl group, if substituted, the alkyl radicals R1 and R2 may also be linked directly or through a heteroatom and alk means an alkylene residue, characterized in that a compound of general formula **(See formula)** which can also be presented in tautomeric form, it is condensed with a compound of the general formula: **(See formula)** with R, X and Y in formulas II and III having the aforementioned meaning and Z means an alkyl group.
