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.
