    Abstract: A process for the photochemical stabilization of fibre materials made of synthetic polyamides, which comprises treating the fibre material with at least one water-soluble copper complex dye or with a mixture of copper complex compounds containing at least one copper complex dye, or containing at least one copper complex dye in combination with a water-soluble 1:2 cobalt complex dye, 1:2 chromium complex dye, or an azo, anthraquinone, nitroaryl or dioxazine dye.The fibre materials treated (dyed) by the process of the invention are distinguished by very high tear strength and elongation values after exposure to light or exposure to hot light.

    Abstract: Radiation (thermal and light)-sensitive polymers are provided which are characterized by the recurring unit of the formula: WHEREIN R'' is lower-alkoxy or phenyl; one of R2 and R3 is hydrogen and the other is WHEREIN A alkylene from 2 to 10 carbon atoms having 2 to 6 carbon atoms between valencies, R'''' lower-alkyl or halogen, x is 1 to 2, y is 0 to 2, and x + y 1 to 3. Water soluble salts also disclosed. The polymers are useful for chemically bonding basic dyestuffs to non-dyereceptive substrates (e.g. polyethylene) by coating the substrate with radiation sensitive polymer and exposing the coated substrate to irradiation. The treated substrate is then contacted with a basic dyestuff which bonds thereto via the free carboxylic groups in the coating. The irradiation can be carried out imagewise to produce an appropriate image on the substrate which image is developed by dissolving out unexposed radiation-sensitive polymer prior to application of the dye. Bonding of the radiation-sensitive polymers of the invention to substrates in the above manner can also be employed as a means of rendering hydrophilic a variety of substrates which are hydrophobic.

    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.
