摘要： This invention relates to ink follower for a water-base ballpoint pen with its bubbles removed, time-dependent stability, less oil separation, and greatly reduced lot-to-lot viscosity difference and associated performance difference, and a method for manufacturing the same. After addition of thickener, the follower is made depressurized preferably at 0.2 atm or lower. Simultaneous heating and stirring are preferable. When the ink follower is solely debubbled in advance, fine bubbles contained in particulate silica, clay thickener, etc. can be very highly removed even if the centrifugal debubbling is not so strong and there is no bad affection to the writing property of the pen. It is also possible that, after adding the thickener, a centrifugal force greater than or equal to 200-fold of the gravitational acceleration is applied to debubble.

摘要： Lot-to-lot or time-dependent instability in quality of the known ink follower for water-base ballpoint pens is overcome. Particulate silica, or organic-treated clay is kneaded as thickener with base oil to prepare gel matter. The gel matter is pressurized to eliminate fine bubbles to yield ink follower for water-base ballpoint pens. The pressurization is preferably performed at 2 atm or higher. The elimination of the bubbles is more effective when the ink follower is, under pressurization, stirred and/or heated.
