が使用されている。Prior art and its problems In recent years, various devices such as facsimile machines, computer terminals, word processors, image printers, printers, etc. have been gaining popularity due to their non-impact and low noise, simple device mechanisms, low cost, and Thermal transfer recording media, that is, heat-sensitive transfer sheets, are widely used because of their high reliability, small size and light weight, and ability to print in color. The heat-sensitive transfer sheet is generally made by forming an ink layer on the surface of a heat-resistant base material such as polyester, which is made by mixing coloring agents and other additives with a room-temperature solid substance (low melting point substance) such as wax that becomes liquid when heated. By aligning a transfer paper with this ink layer and printing with a thermal head, a desired image can be formed on the transfer paper. Similarly, a low melting point substance such as wax is used for the release layer that may be formed between the ink layer and the heat-resistant base material.

高速印字時に地汚れ等の欠点が認められる。First, it has a sharp melting property, is slow to respond to heat from a thermal head, and is inferior in high-speed printing performance and delicacy of printed images. If the melting property is not sharp, the coagulation property is also not sharp, and the assimilation of melt-transferred ink is slow.
Defects such as scumming are observed during high-speed printing.
