PURPOSE:To increase durability and weatherproof properties of images of a recording medium by providing on a thermal recording medium, which has sublimating, vaporizing or fluxing migrating properties, on a substrate, a dye deactivating resin layer which changes a dye in an ink layer deactivated or stabilized. CONSTITUTION:A heat transferring dye which has eutectic temperatures of 50-140 deg.C of a heat fusion ink is preferable. Any dyes such as direct dye, acid dye, basic dye, sulfer dye, vat dye, azoic dye, oil dye, dispersion dye of heat sublimation type and etc. may be used. For deactivation or stabilization of dyes, cellulose group resin, etc. are used for the purposes. If a thermal head 4 is pressed from the side of a supporting member 1, the resin 7 in dye deactivation resin layer 3 moves together with a dye 6 to the surface of the recording sheet 5 and suppresses activity of the dye 6 and stabilizes it. |
