<P>PROBLEM TO BE SOLVED: To provide an inkjet ink composition excellent in curability by ultraviolet irradiation, discharge stability of dot omission, a flight bending, etc., nozzle clogging resilience after being left for a long period of time, and storage stability of ink. <P>SOLUTION: The inkjet ink composition contains, at least: water; a urethane (meth)acrylate; a first radically polymerizable compound whose solubility to 100 g of water at 20°C is 1 g or more; a second radically polymerizable compound whose solubility to 100 g of water at 20°C is less than 1g; and a photoinitiator. The first radically polymerizable compound contained is 1-30 mass% based on the total mass of the ink composition. <P>COPYRIGHT: (C)2013,JPO&INPIT |
