本発明は通電熱転写型のビデオプ゛リンタやサーマルプ
リンタに使用する通電熱転写記録材に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electrically conductive thermal transfer recording material used in an electrically conductive thermal transfer type video printer or thermal printer.

リンタを中心に通電熱転写型プリンタが広く普及してき
ている。2. Description of the Related Art In recent years, electric thermal transfer printers, mainly color printers, have become widely popular because of their low noise and high speed printing capabilities.

熱可塑性樹脂がリッチな層が層状に塗布されていた。The ink layer of the electrical thermal transfer recording material used in electrical thermal transfer printers is a mixture of a low-melting substance such as wax, a thermoplastic resin, and a coloring material, which is coated on a base material. In some cases, a layer rich in wax and a layer rich in thermoplastic resin were applied in layers.

い。However, such electrically conductive thermal transfer recording materials have the disadvantage that images printed on rough paper become unclear. Since rough paper has uneven surfaces, it is not possible to place sufficient ink on the concave surfaces using an electrically heated thermal transfer method that transfers ink through contact. Furthermore, if an ink with an extremely large amount of resin that causes bridging on concave surfaces is used, the ink will not cut easily during transfer, resulting in jagged or blurred outlines.
本発明はかかる問題点を解決し、粗面紙へ鮮明な印画を
得ることが目的である。The object of the present invention is to solve these problems and obtain clear prints on rough paper.

It is fixed to the base layer 1 such as T. Further, on the back side of the ink layer, the paste layer 1 is coated with an energized heat generating layer 1iI2. Here, (a) shows the type of Example 1, and (b) shows the type of Example 2.

。FIG. 3 is a diagram showing the electrically conductive thermal transfer recording material of the present invention transferred to transfer paper. As can be seen from the figure, the wax on the heated surface melts and the resin particles become fused to each other and adhere to the paper surface 8. When the base layer 1 is removed, the unattached side of the resin particles can be removed neatly, resulting in a sharper print. Since the melted resin remaining on the paper side is formed as a surface, it is possible to sufficiently fill the recesses on the paper surface (Fig. 4), and it is also possible to handle rough paper.
