Abstract
A thermal transfer recording medium having a support and two coloring agent layers provided on the same side thereof, in which the first coloring agent layer is a layer containing a resin and a coloring agent coated on the support and the second layer is a layer containing a heat-fusible material and a coloring agent coated on the first layer, and the respective coloring agents in the two layers have isochromatic color tone. The thermal transfer recording medium provides low energy printing at high speed with little decrease in its density even after being used for many copies, thus permitting high density dye transfer images to be obtained over very many times.
