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.
该发明描述了使用基于
水的紫外光固化喷墨打印油墨,其中由于存在三级胺,油墨呈碱性,从而允许完全溶解式酸性光
引发剂的使用,该光
引发剂为I式或IA式(其中R1、R2、R3、n、q和y的定义如本文所述)。光
引发剂和三级胺的组合使得使用紫外LED光源可以快速低剂量紫外光固化
