Abstract (en)
A process for fixing dyes on natural or synthetic polyamide fibre materials, in which the fabric is treated before, during or after dyeing with a solution containing a homo- or co-polymer (I) with repeat units of formula (1), (2) and/or (3). In the formulae, R1-R4 and R6 = H, 1-6C alkylsulphonyl, optionally substituted phenyl, benzoyl or phenylsulphonyl (optionally substituted in the benzene ring) or 1-12C alkyl (optionally substituted with hydroxy, carboxy, cyano, carbamoyl, the group -CONH-(alk)-T, N,N-di-(1-4C alkyl)-carbamoyl, -SO2-Pn-NH2, -SO2-Pn-NHCOR8, -SO2Ph substituted with NH2 and SO3H, amino, -NHR9, -N(R9)2, -N(R9)3<+> Y<-> or -COO-(alk)-T); (alk) = 1-10C alkylene; T = H or amino groups as above; Pn = phenylene; Ph = phenyl; R8, R9 = 1-6C alkyl; Y = anion; R5 = H, benzyl or a 1-12C alkyl group as for R1-R4 etc.; R7 = H or 1-4C alkyl. Also claimed are homo- or co-polymers containing units of formula (7).

Verfahren zur Fixierung von Farbstoffen auf natürlichem oder synthetischem Polyamidfasermaterial, dadurch gekennzeichnet, dass man das Fasermaterial vor, während oder nach der Färbung mit einer Flotte behandelt, enthaltend ein Homo- oder Copolymer mit wiederkehrenden Struktureinheiten mindestens einer der Formeln (1), (2) und (3) <IMAGE> und <IMAGE> worin die Variablen die in den Ansprüchen angegebenen Bedeutungen haben. Die erhaltenen Färbungen und Drucke zeichnen sich durch verbesserte Nassechtheiten ohne Beeinflussung der Nuance und der Lichtechtheit und eine verbesserte Ozonechtheit aus.
