Abstract
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.
