した場合。(Problems to be Solved by the Invention) However, among the coupling agents, the silane coupling agent has high 2-reactivity, and the ink may be damaged by polymerization of the coupling agent itself or reaction with other components in the ink. In addition, titanate coupling agents and aluminum coupling agents are susceptible to hydrolysis because they have an alcokind bond in their structure, and titanate coupling agents in particular are susceptible to pigment particles. Because the bond is reversible, its effectiveness decreases over time, and the dispersibility and fluidity of the ink are impaired, resulting in when used in writing instruments.

きる。For pigments whose surface has been treated with a zircoaluminate coupling agent, dissolve the zircoaluminate coupling agent in an appropriate solvent such as ethanol, add the pigment to this, and stir with a stirrer such as a closed-type homomixer. It is obtained by mixing to form a coupling layer of the zircoaluminate coupling agent on the surface of the pigment particles, and then scattering the solvent. As components other than those mentioned above, a surfactant, a rust preventive dispersion aid, a lubricant, etc. may be used as appropriate.

インキを得ることができる。To give an example, first, a pigment surface-treated with a zircoaluminate coupling agent and an oil-soluble resin, or an oil-soluble resin and a solvent as required, are mixed and dispersed in a roll mill to form a solid or paste. An oil-based pigment ink for writing instruments can be obtained by first producing an ink base, then adding a solvent and other additives as necessary to this ink paste, and mixing and stirring.

本発明に係る筆記具用油性顔料インキが何故分散性に優
れ、かつペン先で目詰りが発生しないかについては以下
の様に推察される。(Function) The reason why the oil-based pigment ink for writing instruments according to the present invention has excellent dispersibility and does not cause clogging at the pen tip is surmised as follows.

てインキの流動性が損なわれずペン先での目詰シが発生
しない。Since the zircoaluminate coupling agent has a high adsorption power to the pigment surface and completely covers the pigment surface, its affinity with the oil-soluble resin and solvent, which are other essential components in the present invention, increases and the dispersibility is excellent. Furthermore, pigments have hydroxyl groups on their surfaces derived from their chemical structure or adsorbed water, and these hydroxyl groups interact with the hydroxyl groups of the zircoaluminate coupling agent, resulting in a strong bond formed by a combination of hydrogen bonds and covalent bonds. Since it forms a strong bond, its effectiveness does not deteriorate over time, and therefore, the fluidity of the ink is not impaired and clogging at the pen tip does not occur.
