PROBLEM TO BE SOLVED: To provide an ink composition for ink jet recording which is excellent in printing stability, ejection stability, and storage stability, and realizes a good image, especially an image excellent in color reproducibility. SOLUTION: This ink composition for ink jet recording comprises at least a colorant, a penetrant, a water-soluble organic solvent, and water, wherein the colorant is obtained by coating a pigment with a resin. The resin is a polymer containing an anionic group, and the content of the pigment with respect to the colorant is in the range of 35 to 90% by weight; and the acetylene glycol-based interface is used as the penetrant. An activator and / or a polysiloxane-based surfactant, wherein the water-soluble organic solvent is an alkyl ether derivative of a polyhydric alcohol having 3 or more alkyl carbon atoms, and / or a 1,2-alkanediol An ink composition comprising at least: |
