PROBLEM TO BE SOLVED: To provide an inkjet ink which does not require an organic solvent and does not require a large exposure system for obtaining a high-quality printed matter. A photoacid generator that generates an acid by light irradiation, a color component, and an acid polymerizable compound that polymerizes in the presence of an acid, and the acid polymerizable compound is represented by the following general formula (1). It is characterized by being a vinyl ether compound. [Chemical 1] (In the general formula (1), R 13 is selected from a vinyl ether group, a group having a vinyl ether skeleton, an alkoxy group, a hydroxyl group-substituted product, and a hydroxyl group, and at least one is a vinyl ether group or a group having a vinyl ether skeleton. 14 is a (p + 1) -valent group having a substituted or unsubstituted cyclic skeleton, and p is a positive integer including 0.
