A water base ink set for ink-jet recording comprises a first ink which contains an anionic dye, and a second ink which contains a cationic dye. At least one of the first and second inks contains at least two glycols selected from the group consisting of diethylene glycol, triethylene glycol, and polyethylene glycol, polyvinyl pyrrolidone, and water. The ink set makes it possible to stably discharge the ink by means of an ink-jet head, and it realizes vivid recording which is highly reliable and highly accurate and which provides good color balance.
