The invention describes the use of a water-based UV curable inkjet printing ink wherein the ink is basic due to the presence of a tertiary amine, allowing the complete dissolution of an acid functional photoinitiator of Formula I or Formula IA (wherein R1, R2, R3, n, q, and y are as defined herein). This combination of photoinitiator and tertiary amine allows the rapid low dosage UV curing of a water-based UV formulation using a UV LED light source.

A multifunctional Type II photoinitiator according to Formula (I):
wherein X represents a structural moiety according to Formula (II):
wherein:
A represents a Norrish Type II initiating group; and
L represents a divalent linking group positioning the Norrish Type II initiating group A and the CR2R3-group in a 1-5 to a 1-9 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 9 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 including the multifunctional Type II photoinitiator are also disclosed.
根据公式(I),一种多功能的二类光引发剂,其中X代表根据公式(II)的结构基团,其中:A代表Norrish Type II引发基团;L代表二价连接基团,定位Norrish Type II引发基团A和CR2R3基团在1-5到1-9位置,其中位置1被定义为A的芳香环或脂环中与L共价结合的第一个原子,位置5到9被定义为CR2R3基团的碳原子,L与之共价结合,但L不含胺基。还公开了包括这种多功能二类光引发剂的辐射固化组合物和油墨。
