Thermal transfer sheet, thermal transfer recording method, thermal transfer recording system, resonance circuit and process for producing the same

Abstract

A thermal transfer sheet is equipped with an approval information of being approved as applicable to the predetermined printer. The thermal transfer sheet is set on a printer and, when a determinator determines that the approval information is correct for the printer, the printer is interlocked with the determinator to work the printer in the state where the thermal transfer sheet is set thereon. In the particularly preferable aspect, a recording part of thermal transfer are worked together with the printer and an approval information is destructed by the heating. A mark of an approval information can be formed of a material which can be detected by the light in a visible light region or an invisible region light, a magnetic material, an electrically-conductive material or a resonance circuit. The resonance circuit is preferably formed by thermally transferring an electrically-conductive layer in a predetermined pattern.
