Abstract
The purpose of the present invention is to provide an active ray-curable inkjet ink capable of further enhancing gloss uniformity, surface curability, and scratch resistance of a formed image. The purpose is achieved by an active ray-curable inkjet ink containing a polymerization initiator, a photopolymerizable compound, and a gelling agent, and that undergoes a reversible sol-gel phase transition by temperature change. The inkjet ink contains a polymerization initiator with a molecular weight of 360 or more, and a polyfunctional photopolymerizable compound. The inkjet ink contains 3.0 mass % or more and less than 8.0 mass % of the polymerization initiator with a molecular weight of 360 or more, 1.0 mass % or more and less than 5.0 mass % of the gelling agent, less than 0.1 mass % of the initiator with a molecular weight of 360 or more, and less than 5.0 mass % of the monofunctional photopolymerizable compound.
