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.
