Abstract
Abstract The invention relates to long-shelflife print pastes containing at least one water-soluble reactive dye of the formula D--(X).sub.m (1) in which D is the radical of an organic dye of the monoazo, polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan, azomethine, nitroaryl, dioxazine, phenazine or stilbene series, X is a fibre-reactive radical of the aliphatic, aromatic or heterocyclic series which is bonded to the radical D either directly or via a bridge member, and m is 1, 2, 3, 4, 5 or 6, and, per fibre-reactive radical X, at least twice the stoichiometric amount of an alkali metal acetate, and to their use for printing cellulosic fibres.
