PURPOSE: To enable a stable travel to be performed and thus achieve a high printing quality even when mounted on an ink ribbon cassette having no driving rollers by allowing a wax ingredient and a silicone resin to be contained in a separation layer. CONSTITUTION: A paint for a separation layer is prepared by dispersing in a toluene solvent 80 pts. poly(ethylene) wax (melting viscosity at 100 deg.C: 6cp, dropping point based on ASTE-D-3104: 87 deg.C), 10 pts. silicone acrylic resin, and 10 pts. ethylene-vinyl acetate copolymer by the use of ball mill. Then, the paint for a separation layer is coated on a PET film (a base material sheet) having a thickness of 2.5μm with a silicone back coat applied thereon in use of wire bar coater to provide a separation layer having a thickness of 1.0μm. |
