This invention relates generally to amido or carbamate substituted 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) substituted with a group comprising a bondable amido/carbamate containing group para- to the point of attachment to the triazine 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 amido or carbamate substituted trisaryl-1,3,5-triazines is also disclosed.
本发明涉及一般的酰胺或氨基甲酸酯取代的三芳基-1,3,5-三嗪及其用途,以保护免受环境力量的降解,包括紫外线、活性辐射、氧化、湿气、大气污染物以及它们的组合。新的三芳基-1,3,5-三嗪类化合物包括连接到三嗪环的芳基环(最好是含有羟基的芳基环,可以自由存在或被阻断以形成潜在的稳定剂,位于连接到三嗪环的邻位)取代一个包含可结合的酰胺/氨基甲酸酯取代基的基团,位于连接到三嗪环的对位。在适当的情况下,这些材料可以通过可结合的官能团与涂料、聚合物、树脂、有机化合物等配方材料反应而结合。本发明还揭示了一种通过加入这种酰胺或氨基甲酸酯取代的三芳基-1,3,5-三嗪来稳定材料的方法。
