Abstract
Abstract Aqueous dyestuff preparation of water-insoluble or sparingly water-soluble dyes are used for the preparation of printing pastes for printing textile material and for printing carriers for transfer printing. These preparations contain at least 10% by weight of water, 25 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 water-soluble aminoplast precondensate, 0.5 to 5% by weight of a non-ionic copolymer of ethylene oxide with a further olefin, oxide said copolymer containing at least 65% by weight of ethylene oxide and having a molecular weight higher than 12,000, as well as, if desired or necessary, further nonionic ingredients.
