Abstract
The invention relates to a process for printing cellulosic fibres or cellulose-containing blend fibres with reactive dyes or dye mixtures which contain a reactive dye and subsequent fixation, which comprises printing these materials with a print paste containing at least one water-soluble reactive dye of the formula EQU 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 salts of aliphatic carboxylic acids having 3 to 18 carbon atoms, and subsequently fixing the print; and to the print pastes used and to their use for printing textile materials.
