者に知られたくない情報がこのフィルムから読み取られ
てしまう危険性がある。[Prior art] Conventionally, there has been a recording method developed in 1973, in which heat-sensitive ink, which is solid at room temperature and reversibly becomes liquid upon heating, is applied onto a polyester film or condenser paper and transferred onto plain paper using a thermal head. This is known from Japanese Patent No. 26245. However, in this method,
Since the applied ink is usually of the same phase, there is a risk that the shape of the printed characters will remain on the film due to ink leakage, and information that you do not want a third party to know may be read from the film.
この点、特開昭５５−４２８８６号公報により、加熱に

記録エネルギーと同量のエネルギーを必要とし、スピー
ドの制限、装置の大型化、コストアップの原因となる。In this regard, Japanese Patent Application Laid-Open No. 55-42886 discloses a method of shaping printing marks formed on an ink film by heating. However, erasing the recorded information trace requires the same amount of energy as the recording energy, which limits speed, increases the size of the device, and increases costs.
いずれにしても記録情報跡の消去のために、装置に余分
な機能を付加することは（ｑ策でない。In any case, it is not a good idea to add extra functions to the device in order to erase traces of recorded information.
一方、前記したように、感熱インキをポリエステルフィ
ルム上に塗布し、サーマルヘッドによって普通紙に転写
した印字像は、一般に光沢がある。On the other hand, as described above, a printed image obtained by applying thermal ink onto a polyester film and transferring it onto plain paper using a thermal head is generally glossy.
光沢のある印字は判読性の点からは好ましくないため、
ツヤ消し印字を行なうことが望まれている。Glossy printing is unfavorable from the point of view of legibility, so
It is desired to perform matte printing.
基材として紙を使用すれば印字の光沢はやや少なくなる
が、なお不十分である。If paper is used as the base material, the gloss of the print will be slightly reduced, but it is still insufficient.
［目的］

た印字像を与える熱転写媒体を提供することにある。[Objective] An object of the present invention is to provide a thermal transfer medium that prevents recorded information traces from being readable and provides a matte printed image without adding any extra functions to the device.

熱転写フィルムを提供するものである。[Structure] In order to achieve the above object, the present invention provides a resin matrix type ink layer mainly composed of a resin, a wax that is difficult to miscible with the resin, and a valley coloring agent on a heat-resistant film, and roughly coats the resin. The present invention provides a thermal transfer film characterized in that a heat-melting ink layer having the same color as the resin matrix ink layer is provided on the matrix ink layer.

消しされたものとなる。In the present invention, the resin matrix type ink layer is a resin matrix filled with colored ink finely, and the ink layer is not transferred, and only the colored ink is matted on the hot melt ink layer. Part of it is transcribed. As a result, no legible printed character shapes remain on the transfer film after transfer, and the transferred image also becomes matte.
