| 摘要 |
A thermal transfer recording medium comprising a thermally-melting layer comprising a polyolefin wax defined in the following items (i) to (iv): (i) the wax comprises an ethylene homopolymer or a copolymer made from ethylene and an alpha-olefin having 3 to 10 carbon atoms, (ii) the wax has a number-average molecular weight (Mn) of 400 to 3,000, the molecular weight being measured by gel permeation chromatography (GPC), (iii) the wax has a melting point of 60 to 120° C., the melting point being measured with a differential scanning calorimeter (DSC), and (iv) the softening point (Ts (° C.)) of the wax and the penetration (Y (dmm)) thereof satisfy a specific relationship expression. The thermal transfer recording medium can provide printed images having a superior sharpness (dot reproducibility) and an improved abrasion resistance at a low energy.
