。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an ink composition for a ballpoint pen that ensures good ink ejection properties by preventing as much as possible the wear of the ball seat due to the rotation of the ball. It is something.
（従来の技術とその問題点）

という欠点を有しており、また水性ボールペ゛ンの場合
、油性のそれとは逆にボテ等の発生はなく瑞々しい鮮明
な筆跡が得られる反面。(Prior art and its problems) Conventional ballpoint pens are known to be oil-based or water-based, but oil-based ballpoint pens have an extremely simple structure, and the amount of ink remaining can be seen at a glance. On the other hand, because it is a highly viscous ink of several thousand to 10,000 PS, the ink does not penetrate well into the writing surface, resulting in smudges and cracked handwriting. Moreover, in the case of water-based ballpoint pen, contrary to oil-based pens, there is no smearing, and on the other hand, fresh and clear handwriting can be obtained.

であるという欠点を有しており。Dye-type inks that use dyes as colorants are insufficient in terms of light fastness and water resistance, and pigment-type inks that use pigments have relatively poor lubricity for the ball seats. is noticeable, resulting in short writing distances, strange noises, and both types require structural problems such as intervening an ink relay member between the ink storage part and the ballpoint pen nib. It has the disadvantage that it tends to be complicated.
油性、水性の両者には夫々一長一短があった。Both oil-based and water-based types have their advantages and disadvantages.
本発明者らはこの様な事情に基き、油性ボールペンのも
つ長所と水性ボールペンのもつ長所両方を兼ね備えた機

顔料タイプのボールペンを得るべく種々研究を重ねたと
ころ、１つの知見としてそのインキの粘度が２５℃にお
いて５０〜２０００Ｃ！ＰＳの範囲内に調製されている
ことが最適であるということを得るに至りた。Based on these circumstances, the inventors of the present invention have developed a pigment-type ballpoint pen that fully utilizes the characteristics of pigments, which are both functionally and economically superior and have both the advantages of oil-based ballpoint pens and water-based ballpoint pens. After conducting various studies to obtain this, one finding was that the viscosity of the ink was 50 to 2000C at 25℃! We have come to the conclusion that it is optimal to prepare the resin within the range of PS.
然し乍ら、顔料を分散したインキの粘度を単に樹脂等に

ルペンチップ内のインキ流通溝がボールによって塞がれ
インキの吐出性に問題を生じ、遂には筆記不能になって
しまうなどの問題を生起せしめることになった。従来の
水性ボールペンにおいては。However, if the viscosity of the ink with dispersed pigments is simply set within the above range using a resin or the like, and the ink is directly filled into a ballpoint pen and used for writing, the ball seat will wear out due to the rotational friction of the ball, causing the ball to sink. However, as a result, the ink flow groove in the ballpoint pen tip is blocked by the ball, causing a problem in ink ejection properties, and eventually causing problems such as the inability to write. In conventional water-based ballpoint pens.

かったものである。Since the ink used has a low viscosity of a few CPS, even if ball sinking occurs, problems with the ink ejection amount can be ignored to some extent due to the capillary force. Even in oil-based ballpoint pens that use ink, the ink itself acts as a lubricant due to its high viscosity, which prevents the ball from sinking and there were no problems with ink ejection. be.

るものである。As is clear from the table above, according to the present invention, the viscosity of the ink can be adjusted to 50 to 2000 C! Even if you set PS and fill a ballpoint pen with this to write, it will prevent the wear of the ball seat due to the rotation of the ball as much as possible, and eliminate the problem of not being able to write due to the ball sinking.Of course, as mentioned at the beginning, The present invention provides an excellent ink composition for ballpoint pens that can have the unique advantages of conventional oil-based ballpoint pens, water-based ballpoint pens, and even pigments.
