<P>PROBLEM TO BE SOLVED: To provide oil-based inkjet ink that not only excels in repellency to a nozzle plate and suppresses deterioration of the nozzle plate, but also performs printing of high printing density. <P>SOLUTION: The oil-based inkjet ink includes at least a pigment, a pigment dispersant, and a solvent. The oil-based inkjet ink further contains (A) a fatty acid or an alkyl phosphoric ester and (B) an amine compound. The component (A) and the component (B) are preferably contained in the total amount of 0.01-5 wt.% based on the total ink amount. The component (A) and the component (B) are also preferably contained with a molar ratio [component (A)/component (B)] of 0.1 to 10.0. A fatty acid ester-based solvent or a fatty acid ester-based solvent and a higher alcohol-based solvent are preferably included as the solvent. <P>COPYRIGHT: (C)2011,JPO&INPIT |
