摘要：
The present invention provides an ink follower for an aqueous ballpoint pen having an ink reservoir for directly preserving an ink, and this ink follower comprises at least a gel-like material having a predominantly viscous response and comprising a less volatile solvent having a viscosity of 5 Pa.multidot.sec or less and a hydrophobic thickening agent, and a solid piece having a specific gravity of 0.80 to 1.10. In addition, the present invention provides a ballpoint pen using this ink follower.The ink follower of the present invention is characterized by using the gel-like material having a high flowability and the solid piece for dispersing and absorbing impact. This ink follower has a strong drop impact resistance, in contrast to a conventional gel-like ink control plug. The aqueous ballpoint pen using this ink follower does not lose its function, even when it is dropped from a shelf at a height of 1.5 m.
