<P>PROBLEM TO BE SOLVED: To provide an oil based inkjet composition which reduces an environmental load, excels in the fixation of the ink fluid to paper and the image reproducibility when printed at a driving frequency of more than 10 kHz, and can obtain high density prints with the use of a solvent containing a vegetable oil instead of the conventional ink solvent in the inkjet oil based ink. <P>SOLUTION: The oil based inkjet composition is an inkjet printer ink composition which discharges the ink at a driving frequency of more than 10 kHz and comprises a pigment, at least one type of a vegetable oil, at least one type of a hydrocarbon solvent, and a diluting solvent comprising an auxiliary solvent which is a help to mixing of the nonpolar solvent and the vegetable oil, and has an iodine number in the range of 90-120. <P>COPYRIGHT: (C)2008,JPO&INPIT |
