Abstract
Process for the preparation of basic azo dyes preferably devoid of water-solubilizing acid groups and in particular of sulfonic acid groups, corresponding to the general formula ** (see formula) ** In which D means the radical of a diazo component optionally provided with azo groups and containing at least one group, optionally quaternized, of amino, hydrazine or etherified hydroxylamino, by amidation or condensation, coupling or quaternization.
