Abstract
Gloss-controllable, radiation-curable inkjet inks cure quickly with minimal radiation exposure, enabling high-printing speed and low surface heating with controllable gloss on the printed image. Ink gloss can be controlled by varying the pinning energy to create the printed images with varied gloss from 10 to 100 gloss unit at 85° gloss measurement angle. After curing, the ink remains flexible on the surface, giving excellent performance on a wide range of surfaces, greatly expanding the range of applications for the ink. A gloss-controllable, radiation-curable inkjet ink may include approximately 8-18% of photo-initiators responding to UVA and UVV (UVA: 320-400 nm wavelengths, UVV: 400-450 nm wavelengths) radiation to initiate free radicals and optionally, other types of photo-initiators and approximately 60-85% of highly flexible mono-functional monomers. The resulting ink is of low viscosity, having excellent flexibility after curing, is low-odor and permits excellent print quality and high productivity on a wide range of surfaces.
