ABSTRACT OF THE DISCLOSURE A thermo-sensitive recording medium comprises a sub- strate and a thermo-sensitive, coloring layer, provided on the substrate, comprising a binder, a colorless or light-colored electron-donating dye, an electron-accepting compound capable of reacting with the electron-donating dye and forming a coloring matter upon heating, and an ester compound obtained from a fatty acid having 20 to 28 carbon atoms and a straight or cyclic alcohol, the ester having a melting point of 50 to 100 °C and one or more non-phenolic hydroxyl groups. Thanks to the ester compound, the coloring sensitivity is improved and the formation of abrasion marks is reduced.
