NON-YELLOWING ORTHO-DIALKYL ARYL SUBSTITUTED TRIAZINE ULTRAVIOLET LIGHT ABSORBERS

摘要

The invention relates generally to pyrimidines and triazines ultraviolet light abosrbers containing a phenolic aromatic groups(s) and a non-phenolic aromatic groups(s) and the use thereof to protect agains degradation by environmental forces, inclusive of ultraviolet light, actinic radiation, oxiddation, moisture, atmospheric pollutants, and combinations thereof. The new class ofpyrimidines and triazines includes two (one) non-phenlic 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 stabiling a material by incorporating the novel pyrimidines and triazines is also disclosed.
