The invention provides aqueous dyestuff preparations of water-insoluble or sparingly water-soluble dyes which may be used for preparing printing pastes to be used for printing textile material as well as for printing supports for transfer printing. The preparations contain at least 10% by weight of water, 10 to 60% by weight of a finely dispersed water-insoluble or sparingly water-soluble dye, 0.1 to 5% by weight of at least one anionic dispersant, and 0.5 to 5% by weight of a non-ionic copolymer of ethylene oxide and a further olefin oxide, said copolymer having an ethylene oxide content of at least 65% by weight and a molecular weight of more than 12,000, and also, if desired, further ingredients.
