| 摘要 |
An oil-based pigment ink composition contains titanium dioxide pigment, mica pigment, dispersant, oil-soluble resin, and organic solvent, whose viscosity at a shear velocity of 76 (l/s) is 50 mPa-s or lower. The ink composition produces writing with sufficient covering property and legibility, does not form hard cakes, and can release ink in a stable manner from the tip of a writing tool. |
