Abstract (en)

[origin: US4383835A] The light fastness of polyamide dyeings can be improved by treating polyamide fibre materials, before, during or after dyeing, with copper complexes of the reaction products of salicylaldehydes with amines (for example cyclohexylamine), or with copper complexes of o-hydroxybenzophenones.

Abstract (de)

Die Lichtechtheit von Polyamidfärbungen läßt sich dadurch verbessern, daß man Polyamidfasermaterialien vor, während oder nach der Färbung mit Kupferkomplexen der Umsetzungsprodukte von Salicylaldehyden mit Aminen (z.B. Cyclohexylamin) oder mit Kupferkomplexen von o-Hydroxybenzophenonen behandelt.
