PROBLEM TO BE SOLVED: To provide an ink composition to be used for active energy ray-curable inkjet printing, which has excellent curability and friction resistance, excellent dissolving property of an initiator, little odor, and a low viscosity preventing wrinkles during cured.SOLUTION: An active energy ray-curable inkjet ink composition is provided, which is an inkjet ink composition comprising a pigment, a polymerizable compound, and a photopolymerization initiator. The polymerizable compound contains an aliphatic ethylenically polymerizable compound by 80 wt.% or more with respect to the total amount of the polymerizable compound, the aliphatic ethylenically polymerizable compound contains at least 2-(vinyloxyethoxy)ethyl acrylate and dipropylene glycol diacrylate, the dipropylene glycol diacrylate is contained by 16 wt.% or more with respect to the total amount of the inkjet ink composition, and the photopolymerization initiator contains acylphosphine oxide by 10 wt.% or more with respect to the total amount of the inkjet ink composition. |
