Abstract
A thermal transfer material is disclosed which is useful in a method for forming a color image comprising selectively melt-transferring at least one 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 multiplicity of micropores in the surface layer thereof to enter each ink in a molten state into the micropores, thereby forming a color image comprising at least one of (A) at least one color region of single color of yellow, magenta and cyan, and (B) at least one color region developed on the basis of subtractive color mixture of at least two of yellow, magenta and cyan. The thermal transfer material comprises at least one of a yellow heat-meltable ink layer, a magenta heat-meltable ink layer and a cyan heat-meltable ink layer provided on a foundation or foundations, each ink layer having a melt viscosity of 20 to 200 cps/90.degree. C. and a coating amount of 0.5 to 2.5 g/m.sup.2, the foundation having a thickness of 1.0 to 4.5 .mu.m and the thermal transfer material having an overall thickness of 2.5 to 7.0 .mu.m. The thermal transfer material gives color images excellent in both color reproducibility an…
