Abstract (en)
[origin: EP0957197A1] The ozone resistance of dyes on polyamide fiber materials is improved by treating the material before, during or after dyeing with a liquid containing a homo- or co-polymer with alkyl-acrylic acid units, especially methacrylic acid units. A process for improving the ozone resistance of dyes on natural or synthetic polyamide fiber materials comprises treating the material before, during or after the dyeing operation with a liquid containing a homo- or co-polymer with repeating units of formula (I), in which: -(-CH2C(R1)(COOH)-)- (I) R1 = optionally substituted 1-4C alkyl
