Solid preparations of metal complex dyes are described, obtained by dissolving or slurrying at least one metal complex dye in water with the addition of an anionic dispersant or dispersant mixture and 1 to 20% by weight, based on the finished preparation, of a nonionic ethylene oxide adduct with a molecular weight of 200 to 5000, and optionally further additives, then mixing the components and spray drying the solution or suspension.n n n Such preparations are easily wettable and are characterized by a cold water dispersibility of ≥ 30 g / l. |
