Abstract

Procedure for the preparation of monoazo dyes of the formula (1) Y-R-N = N-D-Y in which Y-R means a benzene or naphthalene radical provided with sulfonic acid groups; Y-D means the radical of a coupling component of the series, benzene or of the heterocyclic series; a Y stands for a hydrogen atom and the other Y signifies a triazine radical (linked via an amine bridge, especially an amine bridge of the formula -NH-) of the formula **(See formula)** in which A represents a quaternized amine or hydrazine group, of the formula **(See formula)** where X means an anion, characterized by coupling a diazo compound of an amine of the formula Y-R-NH2 in which Y and R have the meaning already stated, with a coupling component of the formula HD-Y in which D and Y have the meaning already stated; or by reacting a dye of the formula (1) already explained, in which all the symbols, except for A, have the same meaning attributed to them before and A represents a halogen atom (in particular, a chlorine or bromine atom), with triethylamine, pyridine, diazabicyclooctane- (2,2,2) or dimethylhydrazine.
