| titleOfInvention | Water-based ink composition for direct liquid writing instrument and direct liquid writing instrument incorporating the same |
| abstract | [PROBLEMS] To improve the wettability of a pen core in a water-based ink applied to a writing instrument having a pen core made of a synthetic resin, and satisfy both ink storage and ink recoverability due to pressure change inside the writing instrument. In addition, there is provided a water-based ink and a direct liquid writing instrument that does not cause the ink spilling phenomenon from the pen tip, and further, the ink ejection property from the pen tip is not stable and the handwriting and the toe are not generated in the handwriting. . SOLUTION: Built in a direct liquid type writing instrument that guides ink to a pen tip through a comb groove-shaped pen core in which an ink guide core for guiding ink from the ink storage unit to the pen tip is arranged at the shaft center. A water-based ink composition, wherein the surface tension of the water-based ink is 30 mN / m or less, and the contact angle of the water-based ink with respect to the flat surface of the pen core disc is 30 ° or more. Water-based ink composition. A direct liquid writing instrument containing the ink. [Selection figure] None |
