Abstract (en)
[origin: US4810254A] The wet-fastness properties of cellulose materials dyed with sulfur dyestuffs is improved by treating the cellulose materials, before, during or after dyeing, with a polymer which is a copolymer or homopolymer of a monomer of the formula <IMAGE> (I) wherein R1 and R2 denote, for example, hydrogen or (C1-C22)-alkyl; R3 and R4 denote hydrogen or methyl; and Y(-) denotes, for example, a monovalent anion.
