Abstract
Abstract Aqueous dye preparations are described which contain 15-40% by weight of dyes, 3-18% by weight of an anionic dispersant of the formula (1), 1-10% by weight of sodium lactate, 1-10% by weight of glycerol and/or propylene glycol, 0.1-5% by weight of a compound having monomer units of the general formula (2), 3-10% by weight of betaine monohydrate, 0-4% by weight of a compound having monomer units of the general formula (3) and 0.1-15% by weight of customary auxiliaries; preparations of this type have a long shelf life, are highly redispersible and do not form sediments; they are suitable in particular for the continuous dyeing of polyester textile materials or mixtures thereof with cellulose textile materials.
