The readily dispersible dye preparations contain water, one or more dyes insoluble or difficultly soluble in water, a nonionic dispersing agent and optionally further additives, and as anionic dispersing agent: (a) a dialkylsulfosuccinate, the alkyl groups of which each contain 3-7 carbon atoms, or (b) a sulfated or sulfonated fatty acid or fatty acid ester of a fatty acid having in each case 10 to 22 carbon atoms, or (c) a fatty amine-oxalkylation product of the formula <IMAGE> wherein Q is an aliphatic hydrocarbon radical having 12-22 carbon atoms, M is hydrogen, an alkali metal cation, ammonium cation or amine salt cation, and m and n are integers, the sum of m+n being at least 2 and at most 50. These preparations are suitable for use in aqueous and also organic printing inks. There are also described aqueous printing pastes which contain lignosulfonate, in addition to the anionic dispersing agents listed under (a), (b) and (c). |
