Abstract
A solvent-based ink jet ink composition includes a coloring material; and a solvent; in which the composition includes, as the solvent, two or more types of solvent that are compounds represented by the following general formula (1), and R1, R2, and R3 have the same structure as one another and m are consecutive integers, in the solvent. R1O—(R2O)m—R3 (1) (in the formula, R1 is a hydrogen atom or an alkyl group with 1 to 6 carbon atoms, R2 is an alkylene group with 2 or 3 carbon atoms, and R3 is a hydrogen atom, an acetyl group, or an alkyl group with 1 to 4 carbon atoms. However, both of R1 and R3 are not hydrogen atoms. m is an integer of 1 to 7.)
