A composition and a process for the production of stable, water dispersions of anionic dyestuffs, for example acid or direct dyestuffs, useful for the dyeing of organic fibers including paper. Highly concentrated, liquid dispersions of at least 15-40% by weight of dry anionic dyestuff are achieved by the use of nonionic dispersing agents and mixing or grinding in a mill until most of the undissolved dyestuff particles are smaller than 10 mu . |
