Abstract
Process for the preparation of organic dyes, characterized in that in organic dyes, preferably water-soluble dyes, or in dyeable compounds, the radical of a pyrimidine sulfonic acid which it contains, bound together with a compound, is introduced by condensation or coupling according to methods already known per se. Carbon atom, at least, of the heterocyclic ring, a halogen atom. (Machine-translation by Google Translate, not legally binding)
