Abstract
A thermal recording medium has two or more kinds of thermo sensitive ink on a base member thereof, and each of the inks has a different melting point and a different color. At least one of the inks also contains an achromatizing agent for concealing a color of at least one of the inks. The thermal transfer recording medium thus constructed is capable of producing multiple colors on a recording sheet by utilizing a device having only one heating head.
