本発明は、通電熱転写印写Ｍ置ｑ通電感熱型インクフィ
ルムに関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an electrically conductive thermal transfer printing M/Q electrically conductive heat-sensitive ink film.
従来、通電感熱型インクフィルムは、例えば、特開昭６

抵抗層、支持体層とインク層からなる構造であった。Conventionally, electrically conductive heat-sensitive ink films have been developed, for example, by
As shown in Japanese Patent No. 0-71293, the structure consisted of a current-carrying resistance layer, a support layer, and an ink layer.
しかし、このような従来の通電感熱型インクフィルムは
、未だ次のような欠点を有している。However, such conventional electrically conductive heat-sensitive ink films still have the following drawbacks.
すなわち、第１に発熱蓋が低いために、記録の高速化に

記録時に通電組成物・基材が浴融して、通電ヘッドに粘
着して、フィルム送りに不都合が生じたり、記録濃度の
低下などの現掌が生じるという欠点があった。Firstly, because the heat-generating lid is low, it is not possible to obtain sufficient recording density as recording speeds increase.Secondly, the current-carrying composition/base material melts in the bath during recording, causing problems with the current-carrying head. This has the disadvantage that it sticks, causing inconveniences in film feeding and problems such as a decrease in recording density.
本発明は、このような従来の欠点を解決するもので、そ

供することにある。The present invention has been made to solve these conventional drawbacks, and its purpose is to provide an electrically conductive heat-sensitive ink film that realizes an increase in recording speed. Another object of the present invention is to provide an electrically conductive heat-sensitive ink film in which the electrically conductive composition/substrate does not stick to the electrically conductive head during recording.

This is a diagram showing the principle of energization by a current-carrying head having a #kL pole 4 and a return electrode 5.
The current-carrying support layer 2 of the recording sheet is pressed into contact with the current-carrying support layer 2, and electricity is applied to generate heat in the resistance layer to raise the temperature.The heat is transmitted through the current-carrying support layer 2, and the temperature of the ink layer 3 rises, causing bath melt flow. By doing so, thermal transfer recording is performed on the recording paper (the recording paper is not shown).
