<p>PURPOSE: To provide an oil-base ink compsn. for a ball-point which not only provides a smooth touch in writing inherent in a low-viscosity ink but also does not cause bleeding nor undesirable outflow. CONSTITUTION: The compsn. at least contains a colorant, an org. solvent, and a stringiness-imparting polymer and has a viscosity of 2,000-10,000mPa.s at 20 deg.C and a length of the ink strings of 100mm or higher at 20 deg.C.</p> |
