Abstract
A thermal transfer magnetic ink, ink sheet and method of printing with the magnetic ink and apparatus which will print high quality images and characters. The heat-fusible magnetic ink transfer sheet includes a heat-fusible magnetic ink layer disposed on a heat resistant support film. The magnetic ink layer includes minute magnetic particles dispersed in a binder and has a surface tension lower than about 20 dynes/cm when melted. The magnetic properties of the ink combined with the melted ink's surface tension, permit avoiding contact between the ink transfer sheet and the recording medium. A magnetic field pulls the ink melted by a print head off of the support film so that the melted ink flies from the ink transfer sheet to the recording medium.
