More specifically, the present invention provides a pigment that exhibits writing properties with little smearing, smooth outflow during use, low tip abrasion, provides a smooth writing feel, and has excellent initial value properties. The present invention relates to a water-based ink composition.
従来の技術
水性インキ用のボールペンは、通常ボール受は座が樹脂
又は金属で作られているため、従来のボールペン用顔料
水性インキ組成物を用いた場合、筆記時にボール回転が

、使い込むとボール受座が摩耗してボールがめり込んで
しまうために筆感が悪くな９、さらには摩耗が進行し、
カシメ部がガタガタに波打って、ボールがチップから脱
落してしまうなどの欠点があった。Conventional Technology Ballpoint pens for water-based ink usually have a ball holder made of resin or metal, so when conventional pigment water-based ink compositions for ballpoint pens are used, the ball does not rotate smoothly during writing. Not only does the ball squeak as it rotates, but the ball seat wears out and the ball sinks in when used, resulting in poor writing feel.9 Furthermore, wear progresses.
There were drawbacks such as the caulking part being loose and undulating, causing the ball to fall off the tip.

It is contained in a range of 0.01 to 0.5 weight. If this content is less than 0.01 weight range, the lubricity of the composition will not be improved sufficiently, and the object of the present invention cannot be achieved.
If the weight range exceeds 0.5, the surface tension of the composition will drop significantly, resulting in ink oozing or bubbling when using a ballpoint pen.

．． If the weight width is less than 5, the pigment dispersion stability, ink lubricity, and stability over time will be poor, and if it exceeds the 10 weight width, the viscosity of the ink will increase, resulting in less ink flowing out during use, making it difficult to write. Sexuality becomes worse.

どが著しく向上する。Effects of the Invention By containing a predetermined amount of a fluorosurfactant and a water-soluble resin, the pigmented water-based ink composition of the present invention suppresses chip abrasion to a low level compared to conventional pigmented water-based ink compositions, and improves initial performance. Brushability, writing performance, brush sensitivity, flowability during use, etc. are significantly improved.

ルダーとの摩擦が減じ、その上ボールを良く濡らす作用
によって、初筆性が良く、かつ良好な書き味を持続し、
筆記性能向上の役割を果たしているものと推察される。The theoretical basis for this effect cannot be clearly explained, but the excellent penetrating action of fluorosurfactants allows the ink to penetrate into the small gap between the ball and the ball holder. A relatively strong thin film of the ink is formed by the water-soluble resin, which reduces the friction between the ball and the ball holder, and also has the effect of wetting the ball well, providing good first-time writing and maintaining a good writing feel.
It is presumed that it plays a role in improving writing performance.
