本発明は感熱記録体に関し、更に詳しくは感熱記録体の
帯電が原因となって発生する通紙トラブル等を防止し、
しかも自然紙の風感を損なわない感熱記録体に関する。Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a thermal recording medium, and more specifically, to prevent paper feeding troubles etc. caused by charging of the thermal recording medium,
Furthermore, the present invention relates to a heat-sensitive recording material that does not impair the feel of natural paper.
（従来の技術）
従来よシ発色性物質と該発色性物質を熱時反応して発色
せしめる顕色性物質とを含有する感熱発色層を支持体上
に設けてなる感熱記録体は良く知られている。(Prior Art) Conventionally, a heat-sensitive recording material in which a heat-sensitive color-forming layer containing a color-forming substance and a color-developing substance that reacts with the color-forming substance under heat to form a color is provided on a support is well known. ing.
かかる感熱記録体はメインテナンスが容易、記録時に臭
気騒音がない、−次発色であるなどの理由により、ファ
クシミリ、プリンターなどの記鉦媒体として広く利用さ
れている。Such heat-sensitive recording media are widely used as recording media for facsimiles, printers, etc. because they are easy to maintain, produce no odor or noise during recording, and exhibit secondary color development.

発生しない合成紙又は合成樹脂フィルムを支持体とした
感熱記録体が種々考えられている。Conventionally, paper has been used as a support for these thermal papers. However, recently, the range of use of thermal paper has expanded9, and it has come to be used in clean rooms and the like. If conventional thermal paper with paper as a support is used for such purposes, it will generate paper dust and cannot be used in clean rooms where even the slightest dust is undesirable. Therefore, various heat-sensitive recording materials using synthetic paper or synthetic resin film as a support that do not generate paper dust have been considered.
このような感熱記録体は紙粉が発生しないうえに平滑性
が高いためドツトの再現性が良く高速性及び中間調再現
性に優れ、耐水性が良いという長所がある。Such a heat-sensitive recording material does not generate paper dust and is highly smooth, so it has the advantages of good dot reproducibility, high speed, excellent halftone reproducibility, and good water resistance.
しかしながら合成紙又は合成向脂フィルムは一般的に紙
に比較して電気抵抗値特に体積抵抗値が高く、これらを
支持体として用いた感熱記録体はその帯電性のために通
紙トラブルを起しやすいという欠点がある。However, synthetic paper or synthetic oil-balanced film generally has higher electrical resistance, especially volume resistivity, than paper, and thermosensitive recording materials using these as a support can cause paper feeding problems due to their chargeability. It has the disadvantage of being easy.

用した場合には以下の新たな問題が発生する。Conventional Japanese Unexamined Patent Publication No. 57-156292, No. 57-170794
, No. 57-199687, No. 59-148693, etc., proposals have been made to solve paper feeding problems caused by charging. It is true that the above proposal solves the paper feeding problem, but when a commonly used conductive agent is used, the following new problem occurs.
一般に導電剤としてはイオン導電性の物質と電子導電性

方従来本業界で知られた電子導電性物質を用いると環境
湿度依存性はないものの着色が著しく、得られる感熱記
録体の外観が損なわれるという問題が生じる。Generally, ionically conductive substances and electronically conductive substances are used as conductive agents, but when ionically conductive substances are used, they are highly dependent on the environmental humidity and require a considerable amount of coating to obtain a sufficient antistatic effect. Problems arise in that it requires a lot of work and that flatness and blocking occur at high humidity. On the other hand, when electronically conductive substances conventionally known in the industry are used, although they are not dependent on environmental humidity, they are significantly colored, resulting in a problem that the appearance of the resulting heat-sensitive recording material is impaired.
