LAMINATED THERMAL TRANSFER MEDIUM FOR CORRECTION Abstract A thermal ribbon particularly suited to be used once for printing at one temperature and for lift-off correction at a lower temperature. The bottom, resistive layer is a blend of an aliphatic polyurethane and a urethane acrylic copolymer with conductive carbon black. The next layer is 1000 angstroms thick aluminum. The next layer is the release layer, of an ethylene organic acid copolymer, a low-melting material. The top layer is an ink layer containing ethylene vinyl acetate and polyethyacrylate. The resistive layer has a light dusting of graphite. Low print currents for both printing and lift-off correction are achieved.
