Abstract (en)

[origin: EP0410724A2] A heat-transfer recording medium is disclosure, which produces no lowering in transfer-density even when the medium is used under such higher-temperature conditions as in a facsimile equipoment 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 (metha)acrylate copolymer, an alpha -olefin-vinyl acetate copolymer, an alpha -olefin-(metha)acrylic acid copolymer, a vinyl acetate polymer, an alkyl (metha)acrylate polymer, a (metha)acrylic acid polymer and a styrene-containing polymer; Group B A polyester resin, a polyurethane resin, a polyvinyl chloride resin and an epoxy resin.
