A polymerizable Type II photoinitiator according to Formula (I):
wherein:
A represents a Norrish Type II initiating group;
L represents a divalent linking group positioning the Norrish Type II initiating group A and the CR2R3-group in a 1-5 to a 1-8 position wherein position 1 is defined as the first atom in the aromatic or alicyclic ring of A to which L is covalently bonded and the position 5 to 8 is defined as the carbon atom of the CR2R3-group to which L is covalently bonded, with the proviso that L does not contain an amine. Radiation curable compositions and inks include the multifunctional Type II photoinitiator.
一种可聚合的二型光引发剂,其化学式为(I):其中:A代表Norrish二型引发基团;L代表二价连接基团,将Norrish二型引发基团A和CR2R3基团定位在1-5到1-8位置之间,其中位置1定义为A芳香或螺环的第一个原子,与L共价键合,位置5到8定义为CR2R3基团的碳原子,与L共价键合,但L不含胺基。辐射可固化组合物和油墨包括多功能二型光引发剂。
