| abstract | PROBLEM TO BE SOLVED: To form a clear handwriting excellent in color development by suppressing set-off and bleeding of the handwriting while making it possible to form a handwriting which exhibits excellent drying property even with a writing instrument containing a water-based pigment ink. To provide possible writing instruments. SOLUTION: The writing instrument contains a water-based ink composition containing a pigment to which a phosphonic acid group is bonded, a surfactant, and water, and the water-based ink composition preferably exhibits 18 to 50 mN / m. As the form of the writing instrument, a ballpoint pen, a marking pen, or a fountain pen is preferable. [Selection diagram] None |
