The instant invention is directed to novel silylated agents having the formula
where Ar and Ar' are independently substituted or unsubstituted aromatic rings, R is a branched or unbranched chain of 1 to 6 carbons, R' and R" are independently C1 to C12 alkyl or mixtures of C1 to C12 alkyl, and n is 1, 2 or 3. The novel dibenzoylresorcinol silylated agents are capable of absorbing ultraviolet light.
本发明涉及新型
硅烷化剂,其式如下
其中 Ar 和 Ar'独立地为取代或未取代的芳环,R 为 1 至 6 个碳原子的支链或未支链,R'和 R "独立地为 C1 至 C12 烷基或 C1 至 C12 烷基的混合物,n 为 1、2 或 3。新型二苯甲酰基
间苯二酚硅烷化剂能够吸收紫外线。
