Abstract
Abstract A thermal transfer recording medium having a thermally transferable coloring agent containing layer coated on a support. The coloring agent containing layer is separated into at least two layers, one of which is the upper layer and the other of which is the lower layer, and the layer farthermost from the support is a thermally transferable layer containing substantially no coloring agent.
