<P>PROBLEM TO BE SOLVED: To provide an ink ensuring fixability even if its surface tension is low and satisfying color development properties and storage stability, an ink cartridge using the ink, and an inkjet recording method. <P>SOLUTION: The ink includes a pigment, a resin to disperse the pigment, a salt, and if desired, a surfactant. The acid value of the resin is 70-140 mgKOH/g. The salt is composed by binding a predetermined cation and a predetermined anion together. A content of the surfactant is ≤0.2 mass% on a total ink mass basis. The surface tension at 25°C of the ink is 33-40 mN/m. <P>COPYRIGHT: (C)2013,JPO&INPIT |
