摘要:
Ink includes water, a pigment, an organic solvent including glycol ether, and a surfactant including a silicone-based surfactant and a salt of sulfo succinic acid dialkyl ester. As measured by maximum bubble pressure technique at 23 degrees C., the dynamic surface tension of the ink at 15 msec is not greater than 31 mN/m and the difference between the dynamic surface tension of the ink at 15 msec and the dynamic surface tension of the ink at 1,500 msec is not greater than 4.0 mN/m.
