摘要： A water based ink composition for a ballpoint pen containing ι-carrageenan in addition to a dye, water and a water-soluble organic solvent. When used in the ball point pen, the ink composition satisfies an ink drooling prevention and a drying resistance which are mutually incompatible functions and is excellent in writing performance regardless of containing a dye as a coloring agent. The ink composition (c) is used, for example, by accommodating a refill (12) whose ink accommodating tube (18) is filled with the ink composition and which is further loaded with an ink backflow-preventing member (20) in the ballpoint pen (10) whose writing edge is retracted and extruded from a front end opening of a barrel (21).

摘要： A water-based ballpoint pen including a specific aqueous ink, a ball, a ballpoint pen tip that holds the ball at a front end of the ballpoint pen tip, an ink follower following the ink with consumption of the ink, and an ink container directly containing the ink and the ink follower. The ink container communicates with a rear portion of the tip. The ink follower includes at least a base oil and a thickener. The ball point pen tip discharges the ink from the top end portion. The ink container supplies the ink to the tip.
