1-Aminoalkyl-imidazolium compounds which contain in the 3-position and on the terminal amino group fibre-reactive groupings which have been formed by the addition of an epihalohydrin. These bireactive imidazolium salts are suitable in particular for improving the dye yield and fastness to wet processing of dyeings and printings which have been produced on cellulose fibre materials with anionic dyes, for example with reactive or direct dyes. |
