Reactive dyestuffs containing a sulphofluoride group are fixed on cellulose by a covalent sulphonic ester linkage. Experimental evidence for this conclusion is afforded by the exchange of such a reactive dye for iodine by treatment of the dyed cellulose with NaI in acetone. This reaction is specific for sulphofluoride dyes.
