ABSTRACT:
An erasable ball-point pen ink is disclosed. The ink is comprised of a rubber component, a volatile solvent, an organic pigment and a nonvolatile solvent, which additionally contains fine powders of silicon dioxide formed by the hydrolysis of silicon tetrachloride, the hydrolysis being carried out by a high temperature gas phase reaction; a semisolid substance; a soft solid substance having a melting point of not more than 130.degree. C.; a combination of fine powders of silicon dioxide formed by the hydrolysis of silicon tetrachloride, the hydrolysis being carried out by a high temperature gas phase reaction, and a semisolid substance; or a combination of fine powders of silicon dioxide formed by the hydrolysis of silicon tetrachloride, the hydrolysis being carried out by a high temperature gas phase reaction, and a soft solid substance having a melting point not higher than 130.degree. C. The ink can be used in a ball-point pen to make it possible to write fine letters and is capable of maintaining highly stable ink traces over long distances compared with presently available ball-point pen inks. The traces produced are even and show good intensity. Further, the ink does not produce substantial wear of ball holder with respect to the pen components. In addition to the excellent writing performances of the disclosed ink it retains the same or better erasability than erasable inks presently available in the market.
