摘要:
A thermosensitive reversible recording material having a thermosensitive recording layer formed on a substrate sheet and including a substantially colorless dye precursor and a color developing agent capable of reversibly color-developing and erasing the dye-precursor, in which the color developing agent comprises an aromatic compound of the general formula (1) and optionally an overcoat layer preferably containing an electron-beam or ultraviolet-ray cured polymer is formed on the thermosensitive recording layer general formula (1): ##STR1## �R=naphthyl or lower alkoxy-substituted phenol group, Y=--NHCO--, --SCONH--, --CONHCO--, --NHCONH--, --OCO--, --NHCOO--, --NHCOS--, --S--, --NHCONHSO.sub.2 --, --O--, --OCSNH--, --CONHNH--, --OCONHSO.sub.2 --, --CO--, --SCSNH--, --NHSO.sub.2 --, --CONHSO.sub.2 --, --OSO.sub.2 --, --NHCSNH--, or --N=CH-- groups, n=integer of 11-30!
