PROBLEM TO BE SOLVED: To provide an active energy ray-curable inkjet ink composition capable of producing a printed matter having excellent adhesive property to a base material.SOLUTION: An active energy ray-curable inkjet ink composition includes a radical-polymerizable monomer (A) and a photoinitiator (B). The radical-polymerizable monomer (A) is at least one kind selected from a compound represented by Formula (1) or a (meth)acrylic ester compound having a side chain of 2-4C alkylene oxide with a hydroxyl group at a terminal. (Ris H or a methyl group; and n is an integer of 1-3.)SELECTED DRAWING: None 【課題】基材に対する付着性に優れる印刷物を形成可能な活性エネルギー線硬化型インクジェットインク組成物を提供する。【解決手段】ラジカル重合性モノマー（Ａ）及び光重合開始剤（Ｂ）を含み、前記ラジカル重合性モノマー（Ａ）が、式（１）で表される化合物又は末端を水酸基とするＣ２−４のアルキレンオキサイドからなる側鎖を有する（メタ）アクリル酸エステル化合物より選択される少なくとも１種である活性エネルギー線硬化型インクジェットインク組成物。（Ｒ１はＨ又はメチル基；ｎは１〜３の整数）【選択図】なし
