Abstract
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 R, R, R, 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.
