An ink jet ink composition which is an aqueous ink includes a resin dispersion, in which the resin dispersion is a polyurethane resin dispersion formed of a polyurethane resin (U) obtained by reacting an active hydrogen atom-containing component (A) containing a high-molecular-weight polyol component (a1) having a number-average molecular weight of 500 or more and an organic polyisocyanate component (B), and the high-molecular-weight polyol component (a1) includes a polyolefin polyol (a11) having a constituent unit represented by General Formula (1) and/or a constituent unit represented by General Formula (2), and a polyester polyol (a12) having a constituent unit represented by General Formula (3). |
