Abstract
Liquid, water-containing dyeing formulation of a reactive dyestuff, which contains 10-50% by weight of C.I. Reactive Blue 19, 5-50% by weight of one or more anionic dispersants from the group of the ligninsulfonates or from the group of condensation products of formaldehyde with naphthalenesulfonic acid or with a naphthalenesulfonic acid which is substituted by 1-3 lower alkyl groups, 1-30% by weight of the sodium salt of anthraquinone-2-sulfonic acid, 1-6% by weight of one or more buffer substances which are incapable of any reaction with the reactive dyestuff which diminishes the dyeing strength, and 38-83% by weight of water.
