［産業上の利用分野］
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、

Moreover, it relates to thermal recording paper that does not impair the feel of natural paper.
［従来の技術］
従来より発色性物質と該発色性物質を熱時反応して発色

に設けてなる感熱記録体は良く知られている。[Prior Art] A thermosensitive recording material in which a heat-sensitive color-forming layer containing a color-forming substance and a color-developing substance that develops color by reacting the color-forming substance with heat 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２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録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, have no odor or noise during recording, and have two colors.

粉の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 mainly used as a support for these thermal papers. However, recently, the range of use of thermal paper has expanded, and it has come to be used in clean rooms and the like. When conventional thermal paper with paper as a support is used for such purposes, it generates 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上に平沿性が
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 has high flatness, so it has the advantages of good dot reproducibility, excellent high speed and halftone reproducibility, and good water resistance.
しかしながら合成紙又は合成樹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油
紙トラブルを起しやＪいという欠点がある。However, synthetic paper or synthetic resin film generally has higher electrical resistance, especially volume resistivity, than paper, and thermosensitive recording materials using these as a support may cause problems with oil paper due to their chargeability. It has the disadvantage of being ugly.

Proposals have been made in various issues and publications to solve paper feeding problems caused by charging. Although it is true that the above proposal solves the paper passing problem, the following new problem occurs when a commonly used conductive agent is used.

る。一方、従来当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 using ionically conductive substances, they are highly dependent on environmental humidity and are difficult to obtain sufficient antistatic effect. However, problems arise in that a considerable amount of coating is required and that stickiness and blocking occur at high humidity. On the other hand, when electronically conductive substances conventionally known in the art are used, there arises a problem that, although they are not dependent on environmental humidity, they are markedly colored and the appearance of the resulting thermosensitive recording material is impaired.

The object of the present invention is to provide a heat-sensitive recording material having the following properties.

ものである。[8! Means for Solving the Problem] That is, the present invention provides a heat-sensitive coloring layer containing a color-forming substance and a color-developing substance that develops color by reacting the color-forming substance with heat on at least one surface of a support. In a heat-sensitive recording material provided with a support, potassium titanate, silicon carbide (
An antistatic layer mainly composed of a conductive material coated with a conductive substance is provided on the surface of the rice (SiC), alumina (AfJ203), silicon nitride (Si3N4), zinc oxide, etc. The present invention relates to a heat-sensitive recording medium characterized by:

帯電防止層の表面抵抗値は２０℃、１５％１（１１の雰
囲気下で１×１０１２Ω以下である。The surface resistance value of the antistatic layer is 1×10 12 Ω or less at 20° C. and in an atmosphere of 15% 1 (11).

しい。The binder used with the conductive material is not particularly limited, including polyvinyl alcohol, and may be water-soluble or solvent-based as long as it meets the purpose of the present invention, but the binder used on the heat-sensitive layer side should be water-resistant. Alternatively, it is preferable to use a material that can be made water resistant.
