PURPOSE:To enable an improvement in durability without lowering visual confirming properties of image information even to a dynamic heating method, by a method wherein a heat-sensitive layer whose transparency is changed reversibly by depending upon a temperature and a specific plastic film are laminated on a base. CONSTITUTION:In a heat-reversible recording medium which can eliminate image information in the case where the image information formed through heat becomes unnecessary, a heat-sensitive layer 2 which is comprised by dispersing an organic low-molecular substance whose transparency is changed reversibly by depending on a temperature is formed within a binder is formed on a base 3. A plastic film 1 which is selected out of a group comprised of a polyphenylene sulfide film, polyethylene naphtholate film, polysulfon film and aramid film and has the glass transition temperature of almost at least 90 deg.C or the melting point of at least 270 deg.C or neither the glass transition point nor the melting point is laminated on the heat-sensitive layer, on which a heat- resistant and lubricus layer 4 is formed further. Hereby, durability of the recording medium is improved further. |
