Abstract

Procedure for obtaining aqueous dispersions of water-insoluble azo dyes, characterized in that it comprises the steps of coupling, in the presence of an anionic dispersing agent, an aqueous solution or suspension of a diazonium compound, obtained by diazotizing a free amine of water-solubilizing groups, with an aqueous solution or dispersion of a coupling component, free of water-solubilizing groups.
