Abstract
A non-aqueous ink jet ink composition is provided that can form an image having excellent weather resistance, abrasion resistance, and coloring property. The non-aqueous ink jet ink composition includes a cyclic ester compound, at least one first solvent represented by the following General Formula (1) and having a flash point of 140° C. or lower: RO—(RO)—R, a second solvent represented by the General Formula (1), and C.I. Pigment Orange-43 (PO-43) as a pigment. In the at least one first solvent represented by General Formula (1), Rand Reach independently represent hydrogen or an alkyl group having 1 to 5 carbon atoms, Rrepresents an alkylene group having 2 or 3 carbon atoms, and m represents an integer of 2 to 6. The second solvent represented by General Formula (1) includes a glycol monoether compound in which at least one of Rand Ris hydrogen. A volume average particle diameter of the PO-43 is 100 nm or more and 400 nm or less.
