Ink jet ink composition and recording method

An ink jet ink composition which is a water-based ink, the ink composition comprising:

• a colorant;
• a surfactant;
• a fixing resin;
• and
• an organic solvent,
• wherein the surfactant includes a silicone-based surfactant having an HLB value of 10.5 or less,
• the fixing resin includes an acrylic-based resin having a glass transition temperature of 35° C. to 95° C.,
• the organic solvent includes a 1,2-alkanediol having 4 carbon atoms or less and an alkanediol having diols at both terminals and 3 to 5 carbon atoms, and
• the organic solvent contained in the ink composition has a weight average standard boiling point of 195° C. to 205° C.
