PROBLEM TO BE SOLVED: To provide a reversible thermal recording material without raising texture density and without lowering erasing performance even in the case of repeatedly using it. SOLUTION: In the reversible thermal recording material having dye precursor for emitting electron to become dye and electron receptive compound on a support in such a manner that color developing state and discoloring sate occurs according to heat treating temperature condition, the recording material comprises hydroxyphenylbenzoic acid or its derivative, organic amino compound and aliphatic urea compound. And, the recording material preferably comprises aliphatic phenon compound. |
