摘要：
There is provided a water-based ink for ink jet-recording containing a pigment; a surfactant; and water, wherein a slope value of the water-based ink at an evaporation rate of 0% is not more than 15%/hour; and a slope value of the water-based ink at an evaporation rate of 30% is not less than 9%/hour, the slope value of the water-based ink being measured by a centrifugal transmission sedimentation method.
