Abstract: The invention relates to a process for the preparation of a storage stable aqueous formulation of anionic dyes, which process comprises treating the aqueous dye solution and/or dispersion with a polymeric anion exchanger, simultaneously and/or subsequently subjecting the resin-bonded dye to a mechanical wet grinding, in the presence of a nonionic dispersant, and adding to the resultant aqueous dispersion the assistants customarily present in the liquid dye formulations.The process makes it possible to precipitate anionic dyes in virtually quantitative yield from aqueous solution and to prepare storage-stable dye dispersions.

Abstract: The invention relates to dyestuff preparations comprising water, a water-insoluble or sparingly water-soluble dye, a dispersant, a humectant, and optionally further additives, wherein said humectant is a compound of the formula I ##STR1## wherein R is a C.sub.1 -C.sub.16 alkyl group which is unsubstituted or substituted by OH, CN, halogen or --N(C.sub.1 -C.sub.4 alkyl).sub.2, and R' is hydrogen or the --CH.sub.2 --CHOH--CH.sub.2 OH group.These preparations are suitable for use in aqueous or aqueous-organic dye liquors or printing inks or also for obtaining printing pastes. After partial or complete dehydration they are also very readily redispersible.

Abstract: 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 ##STR1## 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, andm 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).
