<p>A thermal transfer recording medium includes a sheet-like base member and a hot-melt ink layer containing a colorant and a hot-melt material. The hot-melt ink layer contains a hot-melt material having a melting point Tm of 70 to 90 DEG C, a complex elastic modulus of 10<6> Pa to 10<7> Pa at 100 DEG C, and a pour point Tp of 150 DEG C or more, the hot-melt ink layer is in an amorphous or microcrystalline state and satisfies condition I/I0 </= 0.9 where I is the diffraction peak intensity in a range of 21.3 to 21.5 DEG originated from an ethylene-based crystal and measured by an X-ray diffraction method, and I0 is the halo intensity in a range of 16 to 17 DEG originated from an amorphous part, or the hot-melt ink layer contains a low-melting point crystalline material having a specific acid value and a specific saponification value and 15 to 30 wt% of a specific copolymer resin whose ethylene content is 65 to 80 wt% and a melt index of 60 or less.</p> |
