To provide an ink composition for ink jet recording which is water- base ink favorable in terms of handleability, odor, safeness, etc., has good delivery stability and color-developing properties, and gives an image excellent in hue, storability, stability, and water resistance and free from defects in image quality such as blur of fine lines.
This ink composition, prepared by dissolving or dispersing, in an aqueous medium, an azo dye having a coupling component comprising an aromatic nitrogen-containing 6-membered heterocycle, contains a compound represented by formula (I) (wherein R101 and R102 are each independently an aliphatic group, an aromatic group or the like; R103 is an aliphatic oxy group, an optionally substituted amino or hydroxy group or the like; R101 may combine with R102 to form a 5- to 7-membered ring, and so may R102 with R103 and R103 with R101; and the case when a 2,2,6,6-tetraalkylpiperidine backbone is formed is excluded).
