摘要：
The water-based ink set for ink-jet recording includes a cyan ink and a blue ink with dynamic surface tensions thereof satisfying the following inequalities (ICB), (IICB), (IIICB) and (IVCB) σ30C≦about 49 mN/m (ICB) σ30C+σ30B≦about 100 mN/m (IICB) wherein σ30C is the dynamic surface tension of the cyan ink at a lifetime of 30 ms and σ30B is the dynamic surface tension of the blue ink at a lifetime of 30 ms, σ1000B≧about 36 mN/m (IIICB) σ1000C+σ1000B≧about 70 mN/m (IVCB) wherein σ1000C is the dynamic surface tension of the cyan ink at a lifetime of 1,000 ms and σ1000B is the dynamic surface tension of the blue ink at a lifetime of 1,000 ms.
