Abstract
A thermal transfer recording mediumaccording to the present invention is to obtain a reliable printed matter with no space between picture information and a protective film thereof and has a melting type transfer portionincluding a melting type primer layerwhose main component is styrene vinyl acetate copolymer and a melting type ink layer. Since styrene vinyl acetate copolymer softens or melts by heating to lose mechanical strength thereof, the melting type transfer portionis transferred with ease from a base sheetby heating to form a printing layer. On the surface of the printing layer, a residual resinformed of material of the melting type primer layeris exposed; however, since styrene vinyl acetate copolymer sticks well to a thermoplastic resin existing on the surface portion of a protective portion, there is no space generated between the protective portionand the printing layer
