Also, particularly preferably Is 0.1 to 8 weight 0 /. It is. When the content is less than 0.01% by weight, the effect of easily removing the ink deposits on the ball surface is inferior. When the content is more than 15% by weight, the line is repelled from the ball as a drawing quality, resulting in drawing cracks. In some cases, it becomes easier to cause problems such as
- the ink forms an ink film on a ball such as a metal ball.
- a ball such as a metal ball.
- This problem is particularly remarkable when a pigment is contained. Since it becomes difficult to form an ink film on the surface, there is an effect that blurring during writing is less likely to occur. This phenomenon is due to the fact that it is more difficult to form an ink coating on the metal ball due to the repelling effect of the repelling, so that the fogging in a short time of 1 to 20 minutes is also suppressed. Is also possible.
- the molecular weight of the polypropylene propylene is as large as possible because the addition amount can be reduced and the drawing line drying property can be improved.

- the addition amount of the polypropylene propylene glycol is preferably from 0.01% to 10% by weight, particularly preferably from 0.1% to 10% by weight. In this range, an ink which uses a pigment and easily dries becomes difficult to form an ink film on a metal pole, and thus has a great effect of making it difficult to cause blurring at the time of writing.
- the addition amount is outside the range of less than 0.1% by weight, the effect is poor and the ball may not rotate. If the addition amount exceeds 10% by weight, it depends on the raw materials used. When the amount of non-volatile components in the ink decreases the drying property of the drawn line or makes it easy for strikethrough to occur. There is power S.

- the propylene glycol used here in particular, the propylene glycol having a molecular weight of 1000 or more, acts poorly on pigment dispersion, but has the ability to dissolve the resin or the affinity. This makes it difficult for hard ink deposits to form on metal poles. As a result, blurring in a short time can be improved more than ever.
- polypropylene glycol having a molecular weight of 1000 or more has a low hydrogen bond, and therefore has a lower affinity for water than that of a low-molecular-weight compound. For this reason, it does not adversely affect (increase in hygroscopicity) even the main solvent in the claims that easily absorbs moisture. Based on the above, it was possible to improve the blurring at the time of writing, and to provide a soft oil-based ink composition for ball-bending with excellent brush feel.

Although this effect is unknown, it has a lubricating effect due to the interaction with the raw material of the ink, while the contact between the pole and the seat in the chip hinders the continuous layered discharge of the ink. In addition, it seems that these substances have an effect of suppressing the coating effect.
