Abstract (en)
[origin: US4544372A] The light fastness of dyed polyamide fibre materials, in particular of the type used for manufacturing car seat covers, can be substantially improved by treating these materials, before, during or after the dyeing, with copper compounds of the compounds of the formula <IMAGE> (I) wherein R=H, OH, alkyl or cycloalkyl. The compounds (I) are distinguished by low self-colour and good stability to acid conditions.
