されている。(Prior art) In recent years, facsimiles, printers, etc. have made remarkable progress.
In particular, a thermal recording method using a thermal head and a thermal recording paper coated with a colorless dye such as ristal violet lactone and a 7-ethanol compound, as described in Japanese Patent Publication Sho μj-/≠032, It is widely used in these devices.

ど他の記録方式に比して記録速度が遅いことであり、採
用範囲が高速記録に迄、及んでいないのが現状である。This thermal recording method has many advantages such as primary color development on the recording paper, no need for development, simplification of the recording device, low costs for the recording paper and recording device, non-innocuous recording, and no noise. It established its position as a low-speed recording method. However, a major drawback of thermosensitive recording is that the recording speed is slower than other recording methods such as electrostatic recording, and at present it has not been adopted to the extent of high-speed recording.

熱発色層に伝導さnるに過ぎず、熱伝導の効率は極めて
低い。In thermal recording, the most important reason why high-speed recording is not possible is that heat conduction between the thermal head and the thermal recording paper in contact with the head is not sufficient, and sufficient recording temperature cannot be obtained. The thermal head, which is a collection of dot-shaped electrical resistance heating elements, generates heat in response to recording signals, melting and coloring the thermosensitive coloring layer in contact with the thermal head. In order to obtain clear and high-density recording, it is necessary to have good dot reproducibility, that is, to ensure that the thermal head and thermosensitive coloring layer are in close contact with each other as much as possible, so that heat conduction is carried out efficiently, and the dots are fully compatible with the n1 high-speed recording signal. It is necessary that completely colored dots corresponding to the shape of the dot heating element of the thermal head are formed on the thermosensitive coloring layer. but,
At present, only a few percent of the heat generated by the thermal head is transferred to the thermosensitive coloring layer, and the efficiency of heat transfer is extremely low.
熱ヘッドと感熱発色層がなるべく密着するように、感熱
発色層の平滑性を向上させる方法がいくつか提案されて
いる。Several methods have been proposed for improving the smoothness of the thermosensitive coloring layer so that the thermal head and the thermosensitive coloring layer come into close contact as much as possible.

、ベック平滑度200〜io。Japanese Patent Publication No. 0/II describes that the surface of the heat-sensitive coloring layer is subjected to surface treatment for a Bekk smoothness of 200 to 1000 seconds. Japanese Patent Application Laid-open No. 3 μm 115253 discloses a Bekk smoothness of 200 to io.
0秒ではj−tミリ秒程度の熱ノξルスにしか対応でき

必要であると記載さnている。At 0 seconds, it can only cope with a thermal nozzle of about j-t milliseconds, and for high-speed recording of 7 milliseconds or less, the surface of the thermosensitive coloring layer must be smoothed to a Bekk smoothness of 1100 seconds or more. It is stated that it is necessary.

fcは記録安定性の点で高速記録用には実用性がない。The conventional techniques for improving the smoothness mentioned above improve the smoothness of the heat-sensitive coloring layer only by calender treatment such as super calender, machine calender, cross calender, etc. Calendar treatment is performed on only the base paper, on the base paper and thermal paper, or on the thermal paper only. Thermal paper whose smoothness has been improved through these calender treatments has an increase in sticking and piling as the smoothness improves and the recording density improves, so in reality, the smoothness does not reach an appropriate level. The recording density, sticking, and turning are perfectly balanced. In the prior art, regardless of the level of smoothness, the recording density or fc is not practical for high-speed recording in terms of recording stability.

ある。Sticking is when the thermal head and thermosensitive coloring layer adhere to each other.
Piling is a phenomenon in which a peeling sound is generated and the dot reproducibility is reduced. Piling is a phenomenon in which the thermal melt of the thermosensitive coloring layer is deposited on the thermal head, causing a decrease in recording density and dot reproducibility. Both of these phenomena interfere with stable recording.
又、感熱紙へのカレンダー処理のもう一つの欠点は、圧
力による発色カブリが発生し、記録紙の地肌部分の濃度
が大きくなってしまうことである。Another disadvantage of calendering thermal paper is that color fogging occurs due to pressure, and the density of the background portion of the recording paper increases.

ない。-Currently, there is a limit to the calendering of base paper due to the occurrence of so-called bulges, wrinkles, etc. caused by uneven basis weight. As mentioned above, the smoothing of the heat-sensitive coloring layer and the improvement of recording density by calendering are inevitably limited, and a product that is sufficiently satisfactory for high-speed recording has not been obtained.
