Abstract
The invention relates generally to pyrimidines and triazines ultraviolet light absorbers containing a phenolic aromatic group(s) and a non-phenolic aromatic group(s) and the use thereof to protect against degradation by environmental forces, inclusive of ultraviolet light, actinic radiation, oxidation, moisture, atmospheric pollutants, and combinations thereof. The new class of pyrimidines and triazines includes two (one) non-phenolic aromatic groups with hydrocarbyl groups that are ortho to each other and one (two) resorcinol or substituted resorcinol group attached to a triazine or pyrimidine ring. The pyrimidines and triazines may be included in a polymeric structure. A method for stabilizing a material by incorporating the novel pyrimidines and triazines is also disclosed.
