摘要：
A water base ink for ink-jet recording contains 0.1% by weight to 4.0% by weight of C.I. Direct Yellow 132; not less than 0.5% by weight of glycol ether having a melting point of not more than −45°C.; and a water-soluble organic solvent in which a solubility of C.I. Direct Yellow 132 at 20° C. is not less than 5%. The ink satisfies 0.2≦B/A and 3≦C/A. B/A represents a weight ratio of the glycol ether to the C.I. Direct Yellow 132 contained in the ink, and C/A represents a weight ratio of the water-soluble organic solvent to the C.I. Direct Yellow 132 contained in the ink. The stability in long-term storage after the evaporation of water or at low temperatures can be obtained even when C.I. Direct Yellow 132 is used in the water-base ink for the ink-jet recording.
