<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 a substrate sheet and including, in addition to a substantially colorless dye precursor, a reversibly color-developing and color-erasing aromatic compound of the formula (I), and a color-erasing promoter compound of the formula II. <CHEM> R<1> = naphthyl, phenyl or substituted phenyl group Y = -NHCO-, -SCONH-, -CONHCO-, -NHCONH-, etc., n = 10 to 29, A<1>, A<2> = naphthyl or phenyl group R<2>, R<3> = H, lower alkyl, lower alkoxy, aryl, halogen or aralkyl. <IMAGE></p> |
