Abstract
A process for the photochemical stabilization of undyed and dyed polyamide or polyurethane fibre material that is characterized in that the fibre material is treated with a water soluble, organic copper, manganese or nickel complex that displays an affinity for the fibres. The polyamide or polyurethane fibre material, e.g., textile, that has been so treated retains its stretch characteristics and elasticity even after prolonged periods of illumination. In addition, in the case of dyed material, treatment with the metal complex results in a marked improvement in light-fastness.
