| titleOfInvention | Water-based ink composition for writing instruments and writing instrument containing the same |
| abstract | PROBLEM TO BE SOLVED: To provide a water-based ink composition for a writing instrument that maintains the texture and high-quality feeling of an initial metallic pen tip even after lapse of time and does not impair the appearance, and a writing instrument containing the same. SOLUTION: A water-based ink composition incorporated in a writing instrument in which a metal nib is arranged at a writing tip, having at least a basic dye, water, a carboxyl group, and having a hydroxyl group. A water-based ink composition for a writing instrument which contains an organic acid having 4 to 6 carbon atoms and the pH of the ink is in the range of 1 to 7, and a metal nib is placed on the writing tip containing the ink. Written writing instrument. [Selection figure] None |
