Abstract

Procedure for the production of azo dyes, of general formula: **(See formula)** wherein the thiophene nucleus carries at least one nonionic electron separating substituent and optionally one or more hydrocarbon radicals which in turn can carry substituents, E represents the residue of a coupling component of the arylamine series, naphthol, phenol, acylacetylarylamide, aminopyrazole, 5-hydroxypyrazole, bearing an aliphatic, aromatic or heterocyclic radical in position 1-, or hydroxypyridone, and n has a value of 1 or 2, said dyes being free of sulfonic acid groups, each being carboxylic acid groups attached to the thiophene nucleus or to an aromatic or heterocyclic nucleus present in E or are attached to a saturated carbon atom that is part of a side chain present in E, characterized in that it comprises diazotizing an amine, of formula: **(See formula)** wherein the thiophene nucleus carries at least one nonionic electron-preparing substituent and optionally one or more optionally substituted hydrocarbon radicals and coupling the resulting diazo compound, with a coupling component of the series of arylamine, naphthol, phenol, acylacetylamide., aminopyrazole or hydroxypyridone, the amine and the coupling component together containing one or two carboxyl groups and no sulfonic acid groups.
