Writable ink with organic filler having large particle size

Abstract

A printing apparatus for a cassette accommodating a recording medium such as a tape-shaped recording medium or the like or a cassette accommodating case includes a cylindrical member and a cylindrical pad. The cylindrical member is supplied with an ink which contains an inorganic filler having a comparatively large particle size. The ink is added with a titanate coupling agent or an aluminate coupling agent. The cylindrical member has the concave printing plate formed on its peripheral surface and is supported rotatably. The ink on the concave printing plate is transferred to the cylindrical pad. The cylindrical pad is supported rotatably. The cylindrical pad is brought in contact with the concave printing plate and the surface of the conveyed cassette accommodating the recording medium or the conveyed cassette accommodating case. The ink transferred to the cylindrical pad from the concave printing plate is transferred to the surface of the conveyed cassette accommodating the recording medium or the conveyed cassette accommodating case.
