    Abstract: A process for photochemical stabilization of non-dyed and dyed polyamide fibre material and mixtures thereof with other fibres which comprises treating the fibre material with a fibre-reactive copper complex of bisazomethines prepared from, for example, salicylaldehydes and aliphatic diamines is described. Some of these copper complexes used are novel compounds. The polyamide fibre material, for example textile material, thus treated largely retains its extensibility and elasticity even after relatively prolonged exposure to light. In addition, a clear improvement in light-fastness is achieved in dyed material by treatment with the metal complex.

    Abstract: A process for bleaching textiles which comprises treating stained textiles in an aqueous bath containing at least one water-soluble aluminium phthalocyanine, under irradiation with light and in the presence of oxygen, while either irradiating the bleaching bath direct or subsequently irradiating the moist textiles outside the bath, as well as water-soluble aluminium phthalocyanines containing detergent compositions are described.
