Abstract:
There is provided a water-based ink for ink-jet recording including: a self-dispersible black pigment; a resin-dispersed chromatic pigment including a resin-dispersed magenta pigment and a resin-dispersed cyan pigment; and water. A ratio (Col/Bk) of a solid content mass (Col) of the resin-dispersed chromatic pigment to a solid content mass (Bk) of the self-dispersible black pigment is in a range of 0.24 to 0.73 and a mean particle diameter of the self-dispersible black pigment is greater than a mean particle diameter of the resin-dispersed chromatic pigment.
