摘要： An oil-based ink composition for a ballpoint pen which comprises a colorant, a resin, 0.01 to 1.5 wt % of a high polymerization degree polyvinyl butyral having a polymerization degree of 900 (calculated molecular weight: 60,000) or more, and a solvent selected from among an alcohol having a vapor pressure at 25°C of 0.001 mmHg or higher, a polyhydric alcohol and a glycol ether as a main solvent accounting for 50 % or more of the total solvent; and an oil-based ink composition for a ballpoint pen which comprises a pigment, and polyvinyl butyral as a dispersant, and a solvent having a chemical structure of the formula (1): (1) wherein R , R and R independently represent H or CH3. The former ink composition allows the suppression of dripping phenomenon through the control of inner cohesion of the ink, and the latter ink composition provides smooth feeling of writing and is excellent in fastness properties and the dispersion stability of the coloring pigment.
