Methyl oxirane dibenzoylressorinol UV absorbers

已制备出环氧化的DBR及其各种衍生物，由于其配伍性和溶解性，它们可用于涂料中。这些涂料可以是丙烯酸、环氧或硅酮硬涂层，它们是热或光固体热固性的或各种溶剂类型的热塑性涂料物质。本发明公开的紫外线吸收剂比单纯的二苯甲酰间苯二酚具有更高分子量及低挥发度的优点，因而具有加工优势。 Epoxylated dibenzoyl resorcinol and derivatives thereof show usefulness as UV absorbers in coatings, due to compatibility and solubility. Such coatings can be acrylics, epoxies, or silicone hardcoats which are thermally or photo cured thermoset, or thermoplastic coating materials in a variety of solvent types. The disclosed UV absorbers also have the advantage of a higher molecular weight and lower volatility than dibenzoyl resorcinol alone thus providing processing advantages.
