A thermosensitive image transfer recording medium comprising:
- (a) a support;
- (b) a release layer, formed on said support, comprising a thermofusible material;
- and
- (c) a thermofusible ink layer, formed on said release layer, comprising a thermofusible material, a coloring agent and a filler, with the difference between the refractive index of said filler and the refractive index of the thermofusible material of the ink layer being 0.15 or less.
A multicolor thermosensitive image transfer recording method of obtaining multicolored images using a plurality of thermosensitive image transfer recording media comprising (a) a support, (b) a release layer, formed on said support, comprising a thermofusible material and (c) a thermofusible ink layer, formed on said release layer, comprising a thermofusible material, a coloring agent and a filler, with the difference between the refractive index of said filler and the refractive index of the thermofusible material of the ink layer being 0.15 or less, each recording medium having different colors, said method comprising the steps of:
- successively bringing said thermofusible ink layer of each recording medium into contact with a receiving sheet;
- and
- imagewise transferring said thermofusible ink layer successively with application of heat thereto to said receiving sheet.
