Abstract: The present invention aims to provide an active energy ray-curable ink composition which can constitute a composition having good flowability during printing. The present invention relates to an active energy ray-curable ink composition, containing an allylic polymer, a dispersant, and a pigment, the allylic polymer being produced by polymerizing an allylic compound represented by the following formula (I):





wherein R1 and R2 each represent H or CH3; X represents an a-valent group having an unsubstituted saturated or partially unsaturated four- to eight-membered cyclic backbone; and a represents 2 or 3.
