摘要

There is provided a water-based ink for ink jet recording including a self-dispersible carbon black modified by carboxylic acid group, a water, and a water-soluble organic solvent, wherein a weight concentration of phosphate ion in the water-based ink is not more than 35 ppm. The water-based ink for ink jet recording has excellent water resistance and is capable of lowering or preventing corrosion of a metal member, in an ink jet recording apparatus, contacting with the water-based ink for ink-jet recording.
