Process for the production of salts of stilbene-azo and stilbene-azoxy dyes

摘要

Salts of stilbene-azo and stilbene-azoxy dyestuffs, and mixtures thereof in which the cations are selected from tetra-alkylammonium, tetraalkylammonium in combination with lithium, sodium, potassium or ammonium, and ammonium in combination with lithium, sodium or potassium, have good cold water solubility relative to known salts
