Disclosed is a water-based ink advantageous from the viewpoints of handling, odorlessness, safety, etc., and has particularly high ejection stability, excellent hue, color development, weather resistance, water resistance, ozone resistance, and defects in image quality An ink composition and an ink jet recording method are provided. As a capsule core material, a coloring composition containing at least one hydrophobic dye, at least one hydrophobic polymer, and at least one high-boiling organic solvent is encapsulated, and the following: The capsule wall was formed using a bifunctional isocyanate compound having two isocyanate groups represented by the general formula (A) and a polyfunctional isocyanate compound having three or more isocyanate groups in the same molecule. A microcapsule-containing colored fine particle dispersion characterized by the above. [Chemical 1] [In General Formula (A), Ar represents an arylene group, X represents a single bond or a divalent linking group, R represents an alkylene group, an aralkylene group, or an arylene group, and m represents an integer of 0 to 20. . ] [Selection figure] None |
