| 摘要 |
This invention relates generally to red-shifted trisaryl-1,3,5-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 trisaryl-1,3,5-triazines comprises an aryl ring attached to the triazine ring [and preferably an aryl ring containing a hydroxyl group, either free or blocked to form a latent stabilizer, ortho- to the point of attachment to the triazine ring (2-position) and a hydroxyl group or a moiety joined by an ether linkage para- to the point of attachment to the triazine ring (4-position)] substituted at the 3-position or disubstituted at the 3- and 5-positions with a group comprising an amide and/or an amine. These materials may be incorporated into formulations comprising coatings, polymers, resins, organic compounds and the like. A method for stabilizing a material by incorporating such red-shifted trisaryl-1,3,5-triazines is also disclosed. |
