摘要：
The present invention relates to an aqueous liquid formulation comprising 5-25% by weight of a dye composition comprising 20-100% by weight of Direct Yellow 11 or of a dye obtainable by reduction or thermal treatment of Direct Yellow 11 0-30% by weight of a blue direct dye, 0-30% by weight of a red direct dye, and 0-60% by weight of a brown direct dye all based on the dye composition, and 1-25% by weight of poly-N-vinylformamide and/or of a polymer obtained by polymerization of a mixture of one or more ethylenically unsaturated monomers and >50% by weight of N-vinylformamide based on total monomers, based on the total weight of the aqueous liquid formulation.
