PURPOSE:To enable repeated use of the title material, by providing a heat- resistant adhesive layer comprising a polyvinyl butyral and/or a cellulose ester each of which has a specified softening or melting point between a conductive base film and an ink layer. CONSTITUTION:A conductive base film 1 of a recording material comprises a resistor layer 11 and a conductive thin metallic film 12 serving as a conductive layer. A heat-resistant adhesive layer 3 is provided on the base film 1, and an ink layer 2 is provided thereon. The adhesive layer 3 comprises a polyvinyl butyral resin and/or a cellulose ester resin each of which has a softening or melting point of at least about 150 deg.C (preferably, 180-250 deg.C). The thicknesses of the resistor layer 11, the metallic film (conductive layer) 12, the adhesive layer 3 and the ink layer 2 are suitably 3-30mum, 0.01-0.2mum, 0.5-5mum, and 2-10mum, respectively. |
