Abstract
PURPOSE: To prevent the ink passage of a writing tool from plugging even when the writing tool is left alone after use, by improving the drying resistance of ink by adding 1,3-dimethyl-2-imidazolidinone to an aqueous ink comprising water and a water-soluble dye.
CONSTITUTION: To an aqueous ink containing about 0.1W30wt%, based on the total weight of ink, a water-soluble dye such as an acid dye, a direct dye or a basic dye, is added about 2W50wt%, based on the total weight of ink, and particularly, for inks for writing tools, about 5W40wt% of 1,3-dimethyl-2-imidazolidinone. Thereby, the drying resistance of ink is markedly improved, and even when a capillary writing tool such as a writing tool having a fiber or felt pen point or a fountain pen is left alone with its cap removed, the ink does not plug the passage of the pen point and flows smoothly through the pen point.
