)—, —S— and/or —O—, and wherein R1, R2, R3 and/or R4 can act as a bridging element connecting two or more structural elements. The invention is also related to a process of producing the initiator and to a curable composition comprising the initiator, a process for producing the curable composition a kit comprising a cationically curable composition and the inventive initiator and the use of the initiator or the curable composition comprising the initiator for various applications, especially in the dental field.
该发明涉及一种引发剂,其包括至少一个结构元素,其特征是以下式(I)其中X-是非或低配位的阴离子,R1、R2、R3、R4分别是独立的线性、环状或支链的C1-C20烷基或烷基烯基,其中烷基或烷基烯基中含有的一个或多个亚甲基基团可以被取代为—CO—、—CONH—、—CON(CH3)—、—S—和/或—O—,且其中R1、R2、R3和/或R4可以作为连接两个或多个结构元素的桥接元素。该发明还涉及一种制备所述引发剂的方法,以及包括所述引发剂的可固化组合物,生产可固化组合物的方法,包括阳离子固化组合物和所述创新引发剂的套件,以及引发剂或包括引发剂的可固化组合物在各种应用中的使用,特别是在牙科领域。
