Abstract
A UV-curable aqueous inkjet printing ink composition contains: water-soluble acrylamide-based monomers by 20.0 to 70.0% by mass, water-soluble hydroxyl group-containing monofunctional monomers by 5.0 to 60.0% by mass, and water-insoluble polymerizable compounds by 8.0 to 35.0% by mass, relative to the total mass of all polymerizable components; a photopolymerizable initiator and/or sensitizer by 3.0 to 10.0 parts by mass relative to 100 parts by mass representing the total mass of all polymerizable components; a pigment; and water; wherein the ratio of the water-soluble acrylamide-based monomers and water-soluble hydroxyl group-containing monofunctional monomers, (water-soluble acrylamide-based monomers/water-soluble hydroxyl group-containing monofunctional monomers), is 0.3 to 10.0; and the ink composition has ability to be partially cured by being irradiated with a UV-LED light having a peak wavelength between 365 and 405 nm, to a cumulative light quantity of 100 mJ/cmor less.
