A water-based ink set for ink-jet recording that achieves both reduction of bleeding between black (Bk) ink and yellow (Y) ink and reduction of color unevenness in a mixed color portion when color ink is used. In a water-based ink set for inkjet recording composed of at least Bk ink, Y ink, magenta (M) ink, and cyan (C) ink, a measurement temperature of 25 ° C. by a maximum bubble pressure method and a lifetime of 30 ms to 1000 ms. For the dynamic surface tension of each ink of the same lifetime, the Y ink is Bk ink or more, the difference is 5 mN / m or less, the difference between Y ink and M ink, and the movement of Y ink and C ink. The difference in target surface tension is set to 3 mN / m or more, and M ink and C ink are set lower than Bk ink. [Selection] Figure 1 |
