THERMAL RECORDING MATERIAL AND METHOD

摘要

PURPOSE:To provide a thermal recording material excellent in secrecy preventing the leakage of the data recorded on the thermal recording material to a third person. CONSTITUTION:A thermal recording material 1 is constituted by providing a high temp. color forming thermal recording layer 3 forming a color by high heat energy on a support 2 and a releasable low temp. color forming thermal recording layer forming a color by low heat energy and making the recording image of the high temp. color forming layer impossible to read on the recording layer 3.
