Abstract
This invention provides a water-based ink jet ink and a method to use the ink. The ink yields high-quality and highly-fast images, is stably ejected, is stably printed for a long period of time, and, at the same time, provides easy recovery in maintenance. The water-based ink jet ink has a pigment, 2-10% by mass of an ink soluble resin, 20-45% by mass of a solvent having a surface tension of 25-40 mN/m, and a silicone-type or fluorine-type surfactant. The ink soluble resin contains a carboxyl or sulfonic acid group as an acidic group and has an acid value of 80-300.
