Provided is an active ray-curable inkjet ink composition which exhibits minimal migration of film components to the exterior, produces printed matter resistant to shrinkage, minimizes the odor of printed matter, has outstanding curability, and has excellent blocking resistance. Also provided are an inkjet recording method and printed matter using said inkjet ink composition. The energy ray-curable inkjet ink composition contains: multifunctional (meth)acrylate compound (component A); a bisacyl phosphine compound having a molecular weight of at least 340 and/or an alpha-aminoketone compound having a molecular weight of at least 340 (component B-1); and a compound represented by formula (1) or formula (2) below (component B-2). The composition does not contain a polymerization initiator having a molecular weight of less than 340, or the content of a polymerization initiator having a molecular weight of less than 340 does not exceed 1 mass% of the ink composition as a whole. |
