Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an ink set for ink-jet recording which can improve the optical density of a recorded article (OD value) without producing an insoluble salt.SOLUTION: An ink set contains a water-based ink for ink-jet recording and a treatment liquid. The water-based ink contains a phosphate group-modified self-dispersing pigment, water, and a water-soluble organic solvent. The treatment liquid contains a monovalent metal ion, water, and a water-soluble organic solvent.
