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.
