〔産業上の利用分野〕
本発明は通電窓外記録用抵抗層フィルムに関する。詳し
くは無騒音タイプライタ−、コンピューターのアウトプ
ット、ファクシミリの印字記録用として有用な通電感熱
記録用抵抗層フィルムに関わるものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a resistive layer film for recording outside an energized window. More specifically, the present invention relates to a resistive layer film for electrically conductive heat-sensitive recording, which is useful for use in noiseless typewriters, computer output, and facsimile print recording.
現在、広く用いられている溶融型インクリボンを用いた
溶融転写記録方式又は、感熱紙を用いた感熱発色記録方
式は、熱ヘツドの蓄熱効果のために印字速度に限界があ
り、高速化が不可能である。Currently, the melt transfer recording method using a melt-type ink ribbon or the heat-sensitive color recording method using thermal paper, which are widely used, has a limit in printing speed due to the heat storage effect of the thermal head, and it is difficult to increase the printing speed. It is possible.
更にヘッド内のドツトが大きく微細な印字は困難である
。Furthermore, the dots inside the head are large, making it difficult to print fine print.
通電感熱記録方式は従来の一般的な熱へ・ノドによる熔
融転写記録方式に比べ、へ・ノドによる蓄熱効果が少な
いため、より高速な印字が可能となる。Compared to the conventional melt transfer recording method that uses heat and gutter, the current thermal recording method has less heat accumulation effect due to heat and gutter, making it possible to print at higher speeds.
又、一つの電極の面積が従来の熱へ・ノドの面積に比べ
て1/4と小さく、より微細な印字が可能となる。In addition, the area of one electrode is 1/4 smaller than the area of a conventional heat gutter, allowing for finer printing.
通電感熱記録用抵抗層フィルムとしては従来ポリカーボ
ネート樹脂にカーボンブランクを機械的に分散し、キャ
スティング法、押出法などでフィルム化したものが用い
られている。Conventionally, as a resistance layer film for electrically conductive heat-sensitive recording, a film in which a carbon blank is mechanically dispersed in a polycarbonate resin and formed into a film by a casting method, an extrusion method, or the like has been used.
高速で印字するためにはフィルムの導電性を高くする必

ィルムの機械的物性は、特に降伏点を示さず、破断点伸
度が小さい。In order to print at high speed, it is necessary to increase the conductivity of the film, and for this purpose, it is desirable to use a carbon blank with a high concentration. However, when a polycarbonate resin is blended with a carbon blank at a high concentration and used, the mechanical properties of the film do not particularly show a yield point and have a small elongation at break.
従って、スリット、蒸着、インク塗布等の後加工時及び
通電感熱記録用リボンとして使用しているとき、切断し
てしまう欠点を有していた。Therefore, it has the disadvantage that it may break during post-processing such as slitting, vapor deposition, ink application, etc., or when it is used as a ribbon for electrically conductive heat-sensitive recording.
そこで本発明者らは、かかる上記の問題点を解決すべく
鋭意検討した結果、ポリカーボネート樹脂とカーボンブ

録用爪抗層フィルムが降伏点を示し、破断点伸度が向上
し、更に後加工時、またはリボンとしての使用時に切断
しにくいことを見出して本発明に至った。As a result of intensive studies to solve the above-mentioned problems, the inventors of the present invention found that a nail anti-layer film for electrically conductive heat-sensitive recording, which is made of a polycarbonate resin and carbon black with an elastomer added thereto, shows a yield point. The inventors have discovered that the elongation is improved and that it is difficult to cut during post-processing or when used as a ribbon, leading to the present invention.

Any elastomer such as fluororubber-based, polyisoprene-based, acrylic-based, etc. can be used. Among these, elastomers having an elastic modulus (JIS 6301) of 1 to 100 MP are particularly preferred. The amount of the elastomer added is 0.1 to 25 parts by weight, preferably 1 to 15 parts by weight, per 100 parts by weight of the polycarbonate resin. If the amount added is less than 0.1 parts by weight, the effect of improving the elongation at break is lost, and if it is added more than 25 parts by weight, the volume resistivity becomes high, making high-speed printing impossible.
