Methods for preparing novel dibenzoylresorcinol-based compounds are disclosed, wherein the dibenzoylresorcinol is bonded to the residue of either an alcohol or a carboxylic acid group, via a methylene carboxylate linking group; and wherein the dibenzoylresorcinol is bonded directly to a substituted or unsubstituted aryl group which does not include a pendent hydroxyl group. The groups attached to the dibenzoylresorcinol may contain a wide variety of functional sites which permit further reaction, e.g., copolymerization. The described compounds are very useful as UV light absorbers and may be used to form improved coating compositions which usually include a transparent, polymeric matrix material. The coating compositions may be applied to various substrates, e.g., thermoplastics, to afford a selection of enhanced properties, such as UV light resistance and abrasion resistance.
揭示了制备新型二苯甲酰邻苯二酚基化合物的方法,其中二苯甲酰邻苯二酚通过亚甲基羧酸酯连接基团与醇或羧酸基团残基结合;二苯甲酰邻苯二酚直接与取代或未取代的芳基结合,该芳基不包括一个侧链羟基。连接到二苯甲酰邻苯二酚的基团可能包含各种功能位点,可进一步反应,例如共聚合。所述化合物非常适用作紫外光吸收剂,并可用于形成通常包括透明聚合物基质材料的改进涂层组合物。涂层组合物可应用于各种基材,例如热塑性材料,以提供一系列增强性能,如紫外光抗性和耐磨性。
