Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a water-based recording liquid for ink-jet recording, effective for reducing pH variation even in the case of using a coloring agent having large pH variation with time, unsusceptible to polyvalent metals existing in the recording liquid composition in an extremely small amount and having excellent ejection stability and provide a recording method to use the recording liquid. SOLUTION: The water-based recording liquid at least comprises a coloring agent, water and a water-soluble organic solvent and further comprises a hypophosphorous acid salt.
