摘要： The present invention relates to an aqueous direct dye formulation, comprising (a) 5 to 25 % by weight of a dye composition comprising (a1) 50-99 % by weight of one or more dyes obtainable by reduction or thermal treatment of Direct Yellow 11, and (a2) 1 -50 % by weight of a blue, black and/or red direct dye, (all based on the dye composition); (b) up to 0.9 % by weight of a saturated, cyclic or acyclic water-soluble amine comprising a primary, secondary or tertiary amino group and at least one further functional group selected from primary, secondary and tertiary amino groups, OH groups and ether groups; and (c) up to 0.9 % by weight of urea; and (d) water, wherein the percentages for (a), (b), and (c) relate to the total weight of the aqueous direct dye formulation. The invention moreover relates to a process for their preparation and the use thereof for the dyeing, in particular of paper, as well as paper which has been dyed with this aqueous direct dye formulation.

摘要： The present invention relates to storage stable aqueous dye dispersions, comprising (a) 2.0 to 30.0 % by weight, based on the sum of (a), (b) and (c), of a dye of the formula (3) in which KK is a residue of a coupling component; (b) 0.1 to 20.0 % by weight, based on the sum of (a), (b) and (c), of at least one additive selected from the group consisting of wetting agents, dispersing agents, rheology modifiers, and preservatives; and (c) 50.0 to 97.9 % by weight, based on the sum of (a), (b) and (c), of water. The invention moreover relates to a process for their preparation and the use thereof for the dyeing, in particular of paper.
