Abstract (en)

[origin: WO9967225A1] This invention relates generally to benzocycle-substituted pyrimidines and triazines 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 benzocycle-substituted pyrimidines and triazines comprises a benzocycle attached to the triazine or pyrimidine ring, and preferably an additional aryl ring containing a hydroxyl group, either free or blocked to form a latent stabilizer, ortho- to the point of attachment to the triazine or pyrimidine ring. These materials may, under the appropriate circumstances, be bonded to formulations comprising coatings, polymers, resins, organic compounds and the like via reaction of the bondable functionality with the materials of the formulation. A method for stabilizing a material by incorporating such benzocycle-substituted pyrimidines and triazines is also disclosed.
