Abstract

Process for the production of a salt of an azo-stilbene or azoxy-stilbene dye, containing at least one sulfonic acid group per molecule, in which at least one cation per molecule is an ammonium cation, and the other cations are selected of between tetra-alkyl ammonium cations (substituted or unsubstituted) and alkali metal cations, characterized in that a compound of formula I is condensed, ** (See formula) ** wherein ring A is without further substitution, in the presence of an alkali metal hydroxide or a tetra-alkyl- (substituted or unsubstituted) -ammonium hydroxide.
