摘要：The wet-fastness properties of cellulose materials dyed with sulfur dyestuffs isimproved by treating the cellulose materials, before, during or after dyeing, with apolymer which is a copolymer or homopolymer of a monomer of the formula ##STR1##wherein R.sup.1 and R. sup.2 denote, for example, hydrogen or (C.sub.1 -C.sub.22)-alkyl;R.sup.3 and R.sup.4 denote hydrogen or methyl; and Y.sup.⊖ denotes, for example, amonovalent anion.
