できないため油性化が必要である。When looking at basic dyes as the pigment matrix for the colorant of the oil-based ink, basic dyes are sold in large quantities in the market as dyes for dyeing textiles, and a wide variety of them are available at low prices. However, by blending colorants, it is possible to create colorants with various hues and brightnesses as desired, but if they are water-based, they cannot be used as colorants for oil-based inks. Since it cannot be used, it is necessary to make it oily.

〜８０重量％用いることができる。In this invention, an aliphatic hydrocarbon solvent is used as the solvent. The aliphatic hydrocarbon solvent may have a chain, branched, or cyclic structural formula, and among these, aliphatic saturated hydrocarbon solvents with a boiling point of 60°C or higher are odorless. Moreover, it is preferable because the ink dries less before writing, such as normal hexane, isohexane, normal hebutane, normal octane, isooctane, normal decane, cyclohexane, methylcyclohexane,
Examples include Isopar E (manufactured by Exxon Chemical Co., Ltd., aliphatic saturated hydrocarbon, aniline point: 74° C.), Isopar G (same as above, aniline point: 80° C.), and these can be used alone or in an appropriate mixture. The amount used is usually 40 to 80% by weight, preferably 60% by weight based on the ink composition.
~80% by weight can be used.
