Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は通電感熱転写記録方法に関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to an electrically conductive thermal transfer recording method.
近年、情報が著るしく豊富とな９、その情報の迅速な伝

ムに関し、種々の開発がなされており、通電感熱転写記
録システムもその代表的な一例である。In recent years, information has become extremely abundant9, and the need for rapid transmission and recording of that information has increased, leading to various developments in information management systems such as information processing systems, information transmission systems, and information recording systems. Electrical thermal transfer recording systems are a typical example.
上記記録システムで使用する記録材料としては、ＫＰ、
縁性基材の一面に導電性層が積層され、他面に熱転写性
インク層が積層された記録材料（ＵＳＰ３７４４６１１
号、実開昭５８−１２８０６３号等）が提案されている

大であり、取扱い易い、記録の際は記鎌針から通電すれ

の長所を有している。The recording materials used in the above recording system include KP,
A recording material in which a conductive layer is laminated on one side of a fringe base material and a thermally transferable ink layer is laminated on the other side (USP 3744611
No., Utility Model Application No. 58-128063, etc.) have been proposed. This recording material uses an insulating base material, so it has great strength and is easy to handle.When recording, you only need to apply electricity from the recording needle, and there is no need to use an expensive thermal head. have.
しかしながら、導電性層に通電し該層に発生した熱でイ
ンク層を転写するものなので発生する熱量が小さく、か
つインク層との間に絶縁性基材が介在しているので転写
記録の画像濃度が小さく、解像度が小さいという欠点を
有しており又画像濃度をあげるために記ｌ＆電圧をあげ
ると放電破壊されより解像度が低下するという欠点を有
していた。又通電ｊ８熱転写記録材料はサーマルヘッド
によって転写を行う感熱転写記録材料に比較し価格が高
く普及の妨げとなっていた。However, since the ink layer is transferred by applying electricity to the conductive layer and using the heat generated in the layer, the amount of heat generated is small, and since an insulating base material is interposed between the ink layer and the ink layer, the image density of the transferred recording is It has the disadvantage that the image density is small and the resolution is low, and when the voltage is increased in order to increase the image density, discharge breakdown occurs and the resolution further decreases. Furthermore, the price of the current-carrying J8 thermal transfer recording material is higher than that of a thermal transfer recording material in which transfer is performed using a thermal head, which has hindered its widespread use.
本発明の目的は上記欠点に鑑み、機械強度が大きく、長
尺体にしても破断することがなく取扱い易い記録材料を

ることにある。In view of the above-mentioned drawbacks, an object of the present invention is to use a recording material that has high mechanical strength, does not break even when made into a long body, and is easy to handle, and to obtain recorded images with high image density and resolution at high speed and at low cost. An object of the present invention is to provide an electrically conductive thermal transfer recording method that can be used.
本発明において用いられる記録材料は導電性基材層の一
面に感熱転写層が積層されたものである。The recording material used in the present invention has a heat-sensitive transfer layer laminated on one side of a conductive base layer.
上記導電性基材層は金属箔よりなるが該層は記録する際

り、又記録針から通電された電気が拡散し電気効率が低
下するので２〜３０μｍに限定される。そして上記金属
箔としては、たとえばアルミニウム、ステンレス鋼、銅
、しんちゅう等の箔があげられる。The above-mentioned conductive base material layer is made of metal foil, and since this layer serves as the counter electrode of the recording needle during recording and also serves as the base material of the recording material, if the surface resistance increases, it will no longer function as a counter electrode. Therefore, when the thickness becomes smaller than 10, the surface resistance becomes larger than 10 and it no longer functions as a counter electrode, and the strength decreases and the support function as a base material decreases. The thickness is limited to 2 to 30 .mu.m because if the thickness becomes thicker, the heat generated by the heat-generating sheet will be less efficiently transferred to the heat-sensitive transfer layer, and the electricity applied from the recording needle will be diffused, reducing the electrical efficiency. Examples of the metal foil include aluminum, stainless steel, copper, and brass foils.
上記感熱転写層は通電記録の際の熱によって転写される
層であり、熱可塑性の結着材で形成されるのが好ましい
。The heat-sensitive transfer layer is a layer that is transferred by heat during electrical recording, and is preferably formed of a thermoplastic binder.
上記結着材としては任意の樹脂マトリックスが使用可能
であるが、該層は熱転写されるのであるから、融点が５
０〜１１０℃のものが好ましく、りとえば、パラフィン
ワックス、カルナバワックス、ポリエチレンワックス、
低分子量のポリスチレン及びその誘導体、ダリビニルプ
チラール、塩化ビニル−酢酸ビニル共重合体、ポリアミ
ド、ポリフレタン、ケトンＩｆＪｔ脂、エチレン−酢酸
ビニル共重合体、石油樹脂等があげられる。Any resin matrix can be used as the binder, but since the layer is thermally transferred, it must have a melting point of 5.
The temperature is preferably 0 to 110°C, such as paraffin wax, carnauba wax, polyethylene wax,
Examples include low molecular weight polystyrene and its derivatives, darivinyl petyral, vinyl chloride-vinyl acetate copolymer, polyamide, polyurethane, ketone IfJt resin, ethylene-vinyl acetate copolymer, petroleum resin, and the like.

On the other hand, if the surface resistance ratio increases, the heat generating sheet will be more likely to be destroyed by discharge, so it is preferable that the surface resistance ratio is 102 to 10'.

い。In the present invention, recording is performed by coating the conductive base layer of the recording material with a heat-generating sheet, contacting the heat-sensitive transfer layer with a recording sheet such as paper or plastic film, and contacting the heat-generating sheet with a recording needle and energizing the recording material. The electricity supplied from the recording needle passes through the heating sheet directly below the recording needle, passes through the conductive base material layer, and returns to the counter electrode. At this time, the heat-generating sheet generates heat without being destroyed by discharge, and the heat-sensitive transfer layer is thermally transferred by the heat, thereby obtaining a recorded image on the recording sheet. It should be noted that the recording voltage for current recording is preferably 5 to 1 oov because the higher the recording voltage, the more likely the heat-generating sheet will be destroyed by discharge.

易である。The structure of the electrically conductive thermal transfer recording method of the present invention is as described above, and since heat is generated by the heat-generating sheet, a large amount of heat is generated, and a recorded image with high resolution and high density can be obtained. Since the heat-generating sheet only generates heat and is not destroyed by electrical discharge, it can be used repeatedly, reducing recording costs.Also, since no electrical discharge destruction occurs, there is no generation of soot or bad odor, and there is no risk of destructive substances adhering to the recording needle. Maintenance of the recording device is easy.
