Abstract
An ink jet ink composition according to an embodiment of the present disclosure is an aqueous ink jet ink composition containing a color material, a silicone-based surfactant, and a water-soluble low-molecular-weight organic compound, in which the ink jet ink composition is used for recording on a recording medium that is a low-absorptive recording medium or a non-absorptive recording medium, and the silicone-based surfactant has a cloud point of 30° C. or higher when mixed at a mass ratio of silicone-based surfactant:propylene glycol:water=1:9:90, and has a surface tension of 30 mN/m or less in each of a 0.1% by mass aqueous solution and a 0.1% by mass propylene glycol solution.
