Abstract: STABLE CONCENTRATED SOLUTIONS OF ANTHRAQUINONE DYES IN SOLVENTS WHICH ARE MISCIBLE WITH WATER AND WHICH ARE USEFUL FOR THE PREPARATION OF DYE LIQUORS FOR DYEING NATURAL OR SYNTHETIC POLYAMIDES. FOR DYEING OR PRINTING NITROGEN FIBROUS MATERIAL, FOR EXAMPLE WOOL, SILK OR SYNTHETIC POLYAMIDE FIBERS, IT IS PRINCIPALLY ANIONIC DYES WHICH ARE USED. THESE DYES ARE USUALLY SUPPLIED IN THE FORM OF FINELY GROUND POWDERS, CONTAINING STANDARDIZING AGENTS, WHICH HAVE TO BE DISSOLVED OR DISPERSED IN THE DYE LIQUOR FOR DYEING. APART FROM THE UNPLEANSANT DUST DEVELOPMENT OF THE INTENSELY COLORING DYES CAUDES BY THE POWDER FORM AND THE RISK OF AGGLOMERATION OF THE DYE POWDER, IT IS BY NO MEANS EASY TO DISSOLVE OR DISPERSE THE SOLID DYE IN THE DYE LIQUOR BECAUSE THE DYE USUALLY HAS INADEQUATE SOLUBILITY IN WATER.
