Abstract:
A water-based ink for ink-jet recording includes: a colorant containing a self-dispersible pigment; water; and fumed silica. The blending ratio of the fumed silica to the self-dispersible pigment may be not less than 0.2 and not more than 1 by weight. Using the self-dispersible pigment and the fumed silica in combination can satisfy improved optical density and an excellent discharge property.
