On the other hand, there is a conflicting and difficult problem that suppression of drying is required at the pen tip. Conventionally, in order to solve such a problem, for example, polyglycerin fatty acid ester or the like is added (Japanese Patent Publication No. 62-1987).
No. 34352), and addition of an amino acid derivative (Japanese Unexamined Patent Publication No.
66277) and the addition of an alkylamide or a derivative thereof (Japanese Patent Laid-Open No. 54-72118).

ある。(Means for Solving the Problems) The ink for marking pens of the present invention devised to achieve the above object comprises lecithin (phosphatidylcholine) in an ink composition containing a colorant, a resin and an organic solvent. It is characterized by being added. Here lecithin is a one-stage type (R: alkyl group) The natural lecithin of various degrees of purity extracted from soybean and egg yolk as well as synthetic lecithin can be used, and 0.01 to 5% by weight in the ink composition. Preferably, it is blended at a ratio of 0.05 to 1% by weight. As the colorant, oil-soluble dyes, organic pigments, pigments, and the like generally used in oil-based marking pen inks can be used, and are blended in the ink composition in the range of 1 to 25% by weight. In general, oil-based marking pen inks such as rosin, ester gum, ketone resin, phenolic resin, cellulosic resin, and vinyl polymer are used as resins added for the purpose of adjusting the viscosity of the ink and obtaining fixability on the writing surface. Used in the ink composition, and is blended in the ink composition at a ratio of 0 to 30% by weight. As the organic solvent, lower alcohols, ethers, ketone-based solvents, ester-based solvents, and aromatic hydrocarbon-based solvents generally used for oil-based marking pen inks can be used, and 40 to 98% by weight of the ink composition. Add in the range. In addition, other additives can be freely added as needed.
(作用) レシチンは界面活性を有しペン先のインキ表面に吸着
されて薄膜を形成するので溶剤の蒸発を防ぎ従つてペン
先の乾燥を抑制する。(Action) Lecithin has a surface activity and is adsorbed on the ink surface of the pen tip to form a thin film, so that the evaporation of the solvent is prevented, and thus the drying of the pen tip is suppressed.

Also, the line drying time is not deteriorated as compared with the comparative example, and the original ink performance is not impaired without changing the hue or the like. Furthermore, there is no problem even when used together with a solvent such as lower alcohol or ether having poor solubility, so that there is an advantage that the restrictions on the solvent are eased.
