Abstract: An inkjet ink composition includes water (A), a resin (B), and an organic solvent (C) which has a boiling point of 250° C. or lower, satisfies Expression (C1), and has a nitrogen atom, in which a content mass ratio of the organic solvent (C) to a main resin in the resin (B) is 0.01 or greater and less than 2.0. In Expression (C1), SPB represents an SP value of the main resin in the resin (B) in a unit of MPa1/2, SPC represents an SP value of the organic solvent (C) in the unit of MPa1/2, and |SPC−SPB| represents an absolute value of a difference between SPC and SPB. |SPC−SPB|≤10.0   Expression (C1)

Abstract: An ink composition for performing printing on an impermeable base material, including water (A), a resin (B) which is at least one selected from the group consisting of an acrylic resin, a polyester resin, and a urethane resin, and an organic solvent (C) which has a boiling point of 250° C. or lower, has no nitrogen atom, and satisfies Expression (C1), in which a total content of the organic solvent (C) is in a range of 0.01% by mass to 5.0% by mass with respect to a total amount of the ink composition for performing printing on an impermeable base material. In Expression (C1), SPB represents an SP value of a main resin in the resin (B) in an MPa1/2 unit, SPC represents an SP value of the organic solvent (C) in the MPa1/2 unit, and |SPC−SPB| represents an absolute value of a difference between SPC and SPB. |SPC−SPB|≤10.0  Expression (C1)
