An aqueous ink preferable to ink-jet recording on plain paper. The dry viscosity is 100 mPa ยท s or less. The dynamic surface tension at 10 ms is 45 mN/m or more, and the dynamic surface tension at 1000 ms is 35 mN/m or less. Therefore the drying properties of the ink are excellent, the ink hardly causes bleeding, and the ejection reliability is improved. |
