Thermal transfer recording medium

A multi-time thermal transfer recording medium comprising:

• a base sheet;
• and
• a hot-melt ink layer, formed on said base sheet, containing a colorant and a hot-melt material, which is selectively heated, melted, and transferred to a transfer medium,
• wherein said hot-melt material has a melting point Tm of 70.degree. to 90.degree. C., a magnitude complex modulus of 10.sup.6 Pa to 10.sup.7 Pa at 100.degree., and a pour point Tp of not less than 150.degree. C.

A thermal transfer recording medium comprising:

• a base sheet;
• and
• a hot-melt ink layer, formed on said base sheet, containing a colorant, an ethylene-based crystalline material, and an ethylene-based resin material, which is selectively heated, melted, and transferred to a transfer medium,
• wherein said hot-melt ink layer is set in an amorphous or microcrystalline state and satisfies the following condition:
• I/I.sub.0 .ltoreq.0.9
• wherein I is the diffraction peak intensity in the range of 21.3.degree. to 21.5.degree. originating from an ethylene-based crystal and I.sub.0 is the halo intensity in the range of 16.degree. to 17.degree. originating from an amorphous part when the hot-melt ink layer is measured by X-ray diffraction.
