Complete erasability by means of rubbing with an abrasive containing rubber eraser is achieved by providing a dried, ink printable coating of a selected water soluble thermoplastic resin, particularly a selected cellulose ether, on the surface of the paper to be printed such that the ink does not bleed through to the paper fibers. A computer card is described wherein machine readable indicia are initially printed on the coating which can then be erased after use by rubbing with an abrasive containing rubber eraser, recoated, reprinted and then reused. | |
