摘要:
A method of improving the stability to ozone exposure of dyes on natural or synthetic polyamide fiber materials comprises treating the fiber material, before, during or after dyeing, with a liquor comprising a homopolymer or copolymer having structural repeating units of formula (1) in which R1 is unsubstituted or substituted C1-C4alkyl. The resulting dyeings and prints feature improved ozone fastness with no effect on hue, colour yield and other fastness properties such as light fastness, for instance.
