| 摘要 |
A nonaqueous ink jet ink composition according to the invention includes a solvent including at least one compound represented by the following formula (1), and a pigment including a pigment orange 43 (PO-43), in which a Na amount included in the ink is 5 ppm to 500 ppm.;R1O—(R2O)m—R3 (1)(wherein, in formula (1), R1 and R3 each independently represent hydrogen or an alkyl group having 1 to 5 carbon atoms. However, either R1 or R3 is an alkyl group having 1 to 5 carbon atoms. R2 represents an alkylene group having 2 or 3 carbon atoms. m represents an integer of 1 to 6.) |
