Abstract:
The present invention addresses the problem of providing a non-aqueous inkjet ink composition which can exhibit excellent fine print reproducibility, excellent solid filling properties and excellent anti-mottling properties when printed at a high speed onto an object having a printing surface made from a vinyl polymer, e.g., polyvinyl chloride and an ethylene-(vinyl acetate) copolymer, or the like, and which has excellent jetting stability and excellent dried coating film re-dissolvability. As the solution for the problem, a non-aqueous inkjet ink composition is provided, which comprises a pigment, a pigment dispersant and an organic solvent, wherein the organic solvent comprises a diethyleneglycol alkyl ether acetate and a diethyleneglycol dialkyl ether, the total content of the diethyleneglycol alkyl ether acetate and the diethyleneglycol dialkyl ether is 40 to 80 parts by mass in 100 parts by mass of the non-aqueous inkjet ink composition, and the diethyleneglycol alkyl ether acetate is blended with the diethyleneglycol dialkyl ether in such an amount that the following equation can be satisfied: (the diethyleneglycol alkyl ether acetate)/(the diethyleneglycol dialkyl ether) = 0.25 to 4.5.
