摘要

A water-based ink for ink-jet recording contains a water-soluble colorant; water; and a water-insoluble liquid which is dispersed in the water and of which boiling point is not less than 250 degrees Celsius. The water-based ink may further contain a surfactant. The drying property of the water-based ink is improved and any odor can be lowered.
