Abstract
A process is described for fixing reactive or substantive dyes on cellulosic fiber material, which process comprises treating the fiber before, during or after dyeing with a liquor comprising a homo- or copolymer containing repeating structures of formula ##STR1## wherein the variables have the meanings claimed in the claims. The dyeings and prints so obtained are distinguished by improved fastness to wet treatments.
