    • A heat-transfer recording medium is disclosed, which produces no lowering in transfer density even when the medium is used under such higher-temperature conditions as in a facsimile equipment and is capable of providing an easily readable transferred image having a low surface gloss, as well as having an excellent keep-secrecy and producing few voids. The recording medium comprises a support; a heat-transfer layer, provided on the support, comprising a thermo-fusible substance and a colorant; and a non-transfer layer which is interposed between the support and the transfer layer and comprises a colorant, a thermoplastic polymer selected from the following Group A and a thermoplastic polymer selected from the following Group B:Group A: an .alpha.-olefin polymer, an .alpha.-olefin-maleic anhydride copolymer, an .alpha.-olefin-alkyl acrylate and methacrylate copolymer, an .alpha.-olefin-vinyl acetate copolymer, an .alpha.-olefin-acrylic or methacrylic acid copolymer, a vinyl acetate polymer, an alkyl acrylate or methacrylate polymer, a acrylic or methacrylic acid polymer and a styrene-containing polymer;Group B: A polyester resin, a polyurethane resin, a polyvinyl chloride resin and an epoxy resin.
