Abstract
Abstract A heat-sensitive transferring recording medium comprises a base film, a heat melting ink layer provided on the under surface of the base film and a conveyance improving layer composed of a material selected from fatty acids, fatty acid derivatives, fatty alcohols, alkali metal salts of mono- or di-alkyl phosphoric acid esters of 8 - 18 carbon atoms, polyester copolymers, and other phosphoric acid esters.
