Water-based ballpoint ink composition and water-based ballpoint pen using the same |
| abstract |
The problem described by the present invention is to provide an ink composition for water-based ballpoint pens whose use allows satisfactory handwriting, less susceptible to ink leakage, and without smudging or splitting on the line, and which has excellent storage stability; and a water-based ballpoint pen containing the ink composition. The solution according to the invention relates to an ink composition for water-based ballpoint pens, which comprises water, a dye and a copolymer having a specific structure; and a water-based ballpoint pen that contains the ink composition. |
