Covalent bonds can be established under alkaline conditions between cellulose and dyes containing nucleophilic groups by employing cross–linking agents which are able to provide several positively charged carbon atoms. Examples are given of various cross–linking agents and dyes. The reaction gives a high colour yield and is the basis for the new Basazol (BASF) range of dyes. These dyes give strong prints on cotton and regenerated cellulose fibres, and possess good fastness properties.
