THERMAL REVERSIBLE RECORDING MATERIAL, PRODUCTION THEREOF, THERMAL REVERSIBLE RECORDING MEDIUM AND RECORDING APPARATUS USING THE SAME

摘要

PURPOSE: To provide a thermal reversible recording material having a wide temp. range for forming a transparent state, easy in temp. control and capable obtaining stable transparency even when recording/erasing processing is repeated. CONSTITUTION: A thermal reversible recording medium has a heat historytransparency characteristic showing the max. transparency when the medium is quenched (e.g. 50 deg.C/sec or more) after heated to temp. T2 and showing the min. transparency when the medium is quenched (e.g. 50 deg.C/sec or more) after heated to the temp. range from T1 (T1
