A pigment ink for ink-jet recording comprises a pigment, a polyethylene oxide-containing dispersing agent, a water-soluble organic solvent, polyethylene oxide, and water. In place of polyethylene oxide, it is possible to use a water-soluble compound having a structure in which two or three hydroxyl groups are joined to a hydrocarbon having a number of carbons of 4 to 6. The ink does not cause any head clogging, and it is excellent in printing quality.
