A thermal transfer medium is disclosed which is useful in a method for forming a color image by selectively melt-transferring at least two of a yellow heat-meltable ink layer, a magenta heat-meltable ink layer and a cyan heat-meltable ink layer onto a receptor having a microporous surface layer. The thermal transfer medium includes a foundation having thereon a yellow heat-meltable ink layer, a magenta heat-meltable ink layer and a cyan heat-meltable ink layer, a non-transferable undercoat layer being provided between the foundation and the respective ink layers, each of the ink layers comprising a coloring agent and a vehicle comprising a wax as a major ingredient, each of the ink layers having a melt viscosity of 20 to 200 cps/90 .degree. C., the undercoat layer comprising a resin exhibiting a strong adhesion to a wax. The thermal transfer medium gives highly fine color images excellent in gradation quality and color reproducibility on the basis of subtractive color mixture of yellow, magenta and cyan.

Thermal transfer medium

A heat-melt transfer recording medium including a foundation, and a release layer, a barrier layer and a colored ink layer provided on the foundation in that order from the foundation side, the release layer including a wax-like substance, the barrier layer being a substantially colorless layer including a thermoplastic resin and containing substantially no wax-like substance, and the colored ink layer including a vehicle containing not less than 50% by weight of a thermoplastic resin. The transfer recording medium has excellent transfer sensitivity and produces print images having excellent smear resistance, abrasion resistance and alcohol resistance.
