Provided is a nonaqueous inkjet ink composition having exceptional wetting properties and fixing properties, as well as exceptional consistency of ejection, even in cases in which high speed printing is carried out on printed matter the printing surface of which comprises a vinyl polymer, such as polyvinyl chloride or an ethylene-vinyl acetate copolymer. This nonaqueous inkjet ink composition contains a binder resin, a pigment, a pigment dispersant, and an organic solvent, wherein the nonaqueous inkjet ink composition is characterized in that the organic solvent contains diethylene glycol ethyl methyl ether at a level of 40-80 mass% in the nonaqueous inkjet ink composition, and propylene carbonate at a level of 7-50 mass% in the nonaqueous inkjet ink composition (but in no instance contains an acetylene based surfactant). |
