[origin: EP0812949A2] A process for fixing reactive or substantive dyes on cellulose-containing fibre material, in which the material is treated before, during or after dyeing with a liquid containing a homo- or copolymer (I) with repeat units of formula (1a), (1b) or (2), in which R1 = 1-12C alkyl, optionally substituted with OH, COOH, CN, carbamoyl, -CONH-(alk)-T, N,N-di-(1-4C alkyl)- carbamoyl, aminophenylsulphonyl, amino, -NHR3, -N(R3)2, -N(R3)3<+>Y<->, -COO-(alk)-T or -SO2-C6H3(NH2)(SO3H) (group A); T = H, -NH2, -NHR3, -N(R3)2 or -N(R3)3<+>Y<->; R3 = 1-8C alkyl; Y = anion; (alk) = 1-10C alkylene; R, R2 = H, benzyl, or as listed for R1.
