<p>PURPOSE:To obtain an oil-based ink, comprising an oil-soluble dye, a lower aliphatic alcohol, a diethylene glycol alkyl ether (acetate) and a specific resin, excellent in fixing properties of scripts and stability with time and hardly causing clogging of pen points. CONSTITUTION:The objective ink comprises (A) an oil-soluble dye (e.g. C. I. Solvent Black 7), (B) a <=4C aliphatic alcohol (e.g. methyl alcohol) as a solvent, (C) a diethylene glycol alkyl ether and/or a diethylene glycol alkyl ether acetate and (D) a resin selected from a ketone resin, a phenolic resin, a rosin resin, a butyral resin and a polyamide resin. The amounts of the components based on the total amount of the oil-based ink are preferably 2-20wt.% component (A), 40-90wt.% component (B), 5-20wt.% component (C) and 1-20wt.% component (D). This ink is preferably obtained by stirring and mixing the respective components with a stirrer and uniformly dissolving the components.</p> |
