Reusable printing medium and apparatus and method employing the same

摘要

An aspect of the invention is related to an erasable image receiving medium comprising:
a substrate comprising paper or film; and
a coating providing an image receiving surface on the substrate, the coating able to (i) receive a marking agent forming an image on the image receiving surface and (ii) allow the marking agent to be selectively removed from the image receiving surface in response to an applied erasing operation, wherein the image receiving surface exhibits a kinetic coefficient of friction while moving at about 6 in/min relative to a stainless steel plate, of less than about 0.3, and the medium exhibits a surface resistivity of between about 106 to about 1013 Ohm/Square, and the coating comprises at least one of silicones, fluorocarbons, olefins, long chain hydrocarbons, amides, and waxes;
a method of using an erasable image receiving medium; a corresponding system and an erasable marking agent.
