WATER-BASED INK COMPOSITION FOR BALL-POINT PEN |
摘要 |
A water-based ink composition for a ball-point pen comprises: a colorant selected from dyes or pigments; a water-soluble organic solvent; water; and a metal salt and/or an amine salt of N-acyl sarcosine. This ink can effectively prevent the wear of a ball seat of the pen caused by the rotation of a ball of the same to make it possible to keep good ink-discharging properties of the pen, whereby a smooth writing of the pen can be performed.
