<p>A thermosensitive reversible recording material capable of forming and holding clear colored images with a high contrast and capable of being repeatedly color-developed and color-erased many times, has a thermosensitive recording layer formed on substrate sheet and including (A) at least one reversibly color-developing and-erasing compound selected from those of the formulae (I), (II) and (III), and (B) at least one dye precursor compound of the formula (IV). <CHEM> R<1> = naphyl or lower alkoxy-substituted phenyl group Y<1>, Y<2> = -NHCO-, -SCONH-, -CONHCO-, etc., n, m, p = 10 to 29, R<2>, R<3>, R<4>, R<5> = C1-C9 alkyl, C3-C6 cycloalkyl or substituted or non-substituted phenyl group, R<6>, R<7> = C1-C6 alkyl or phenyl group. <IMAGE></p> |
