PROBLEM TO BE SOLVED: To provide an inkjet ink excellent in adhesion and scuff resistance of a printed image thereof and capable of achieving higher image quality.SOLUTION: An inkjet ink contains at least a pigment, a resin, water, a solvent and a surfactant. The ink contains as the solvent a water-soluble solvent, and a solvent with a cyclic structure comprising a cyclic sulfone, a cyclic lactam, a cyclic imidazolidinone or a cyclic lactone within a range of ≥5 wt.% relative to a total amount of the ink, contains as the surfactant a surfactant A capable of reducing the surface tension of a liquid comprising 1 wt.% of the surfactant, 40 wt.% of 2-pyrrolidone and 59 wt.% of water to a range of ≤24 mN/m within a range of 0.001-0.1 wt.% relative to a total amount of the ink, and has a surface tension within a range of ≥25 mN/m. |
