    摘要: A process for the preparation of dyes of formula (1) as indicated in claim 1 or of mixtures of such dyes is described.The dyes of formula (1) are obtained by reacting 1,4-diaminoanthraquinone-2,3-dicarboximide, or the corresponding monoimino compound, with an amine and in the absence of a solvent. Dye mixtures are prepared by subsequently partially transamidating the resultant product.

    摘要: There is described a process for the preparation of highly concentrated aqueous solutions of specific cationic azo dyes. The solutions are prepared by diazotising a diazo component in a solution which contains sulfuric acid, coupling the diazotised component to a coupling component, treating the resultant azo dye with a bicarbonate, and converting the dye bicarbonate with an organic acid into the dye salt of said acid.
