Provided is a water-based ink set for ink-jet recording for reducing
bleeding between a black (Bk) ink and a yellow (Y) ink and for reducing
color unevenness in a portion formed by color mixing of color inks. The
water-based ink set for ink-jet recording includes at least a Bk ink, a Y
ink, a magenta (M) ink and a cyan (C) ink. In this configuration, the
following relationships are satisfied: (1)
.sigma..sub.1000Bk.gtoreq.35 mN/m; (2)
|.sigma..sub.30Y-.sigma..sub.30Bk|.ltoreq.5 mN/m; (3)
.sigma..sub.30M.gtoreq.30 mN/m, .sigma..sub.30C.gtoreq.30 mN/m; (4)
.sigma..sub.30Y>.sigma..sub.30M, .sigma..sub.30Y>.sigma..sub.30C;
and (5) .sigma..sub.30Y+.sigma..sub.30M.ltoreq.93 mN/m,
.sigma..sub.30Y+.sigma..sub.30C.ltoreq.93 mN/m, wherein .sigma..sub.30Bk,
.sigma..sub.30Y, .sigma..sub.30M and .sigma..sub.30C are dynamic surface
tensions of the Bk ink, the Y ink, the M ink and the C ink, respectively,
at a lifetime of 30 ms as measured by a maximum bubble pressure method at
a measurement temperature of 25.degree. C., and .sigma..sub.1000Bk is a
dynamic surface tension of the black ink at a lifetime of 1,000 ms as
measured by the maximum bubble pressure method at a measurement
temperature of 25.degree. C.
