<p>A method of manufacturing an ink follower for water-base ballpoint pens, in which a thickener is constant in dispersibility for each manufacturing lot and viscosity variation is small and in which minute bubbles present in the thickener contained in the ink follower are removed, the method involves the step of uniformizing the thickener at any temperature in the range of 40 °C to 130 °C, preferably, in the range of 100 °C to 130 °C.</p> |
