Abstract
Abstract Translated from German 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. The lightfastness of polyamide dyeings can be improved by treating polyamide fiber materials with copper complexes of the reaction products of salicylaldehydes with amines (e.g. cyclohexylamine) or with copper complexes of o-hydroxybenzophenones before, during or after dyeing.
