Abstract (en)
[origin: EP0447352A1] A process for improving the dye yield and the wet fastness of dyeings or prints produced with anionic dyes on cellulosic fibre material, in which the fibre material is treated before dyeing or during dyeing with a quaternary ammonium salt of the formula <IMAGE> in which R denotes C1-C3-alkyl, X denotes the group <IMAGE> Hal denotes a halogen atom and Q<(-)> denotes the anion of an aromatic sulphonic acid or a C1-C3-alkylsulphate ion.
