The present invention relates to novel carbamate containing trisaryl-1,3,5- triazines and the use thereof as an ultraviolet light absorber. In particular, the presently claimed compounds comprise a carbamate triazine polymer which is particularly useful, either alone or in combination with other additives, including other ultraviolet light absorbers and stabilizers, in stabilizing a polymeric film or molded article from degradation due to exposure to actinic radiation.
L'invention concerne un nouveau carbamate contenant des trisaryl-1,3,5-triazines et son utilisation en tant qu'absorbeur de lumière ultraviolette. Les composés de l'invention comprennent notamment un polymère de triazine carbamate qui, pris isolément ou en combinaison avec des additifs tels que d'autres absorbeurs et stabilisateurs de la lumière ultraviolette, s'utilise pour stabiliser un film polymère ou un article moulé afin de le protéger contre la dégradation due à l'exposition à la radiation actinique.
