PROCESS FOR THE PREPARATION OF CONCENTRATED AQUEOUS SOLUTIONS OF CHROMIUM COMPLEXES OF AZO OR AZOMETHINIC DYES BEARING SULFO GROUPS
1. Process for the preparation of concentrated aqueous solutions of the chromium complexes of dyestuffs of the formula see diagramm : EP0088271,P4,F1 in which R1 = H or NO2 R2 = see diagramm : EP0088271,P4,F2 or see diagramm : EP0088271,P4,F3 or of alkali metal salts thereof, by alkaline coupling an...
