O.Z. 0050/40555 Chemically modified proteins obtainable by reacting casein, collagen, gelatin, albumin or mixtures thereof (a) with 0.5 to 15% by weight of chlorine or of a com pound which liberates chlorine under the reaction conditions, in an aqueous medium at a pH of from O to 7 or (b) with 0.5 to 50% by weight of a non-aromatic mono- or disulfonic acid which contains in its organic radical one or more groups or structural feature which react with nucleophiles, in an aqueous medium at a pH of from 6 to 14, are used as dispersants in colorant formulations.
