Abstract
A method of fixing dyes on natural or synthetic polyamide fiber material, wherein the fiber material is treated, before, during or after dyeing, with a liquor comprising a homo- or co-polymer having structural repeating units of at least one of formulae (1), (2) and (3) ##STR1## wherein the variables are as defined in the claims. The resulting dyeings and prints are distinguished by improved fastness to wetting, without the shade and the fastness to light being affected, and by improved fastness to ozone.
