られることが予想される。"Prior Art and Problems" The thermal recording method is widely used in facsimile machines and printers because it allows the recording device to be made smaller and more compact, has a high reliability, and has low running costs for recording paper. It is used. - With the advancement of the information society, the need for mobile connectivity has become apparent, and services such as car telephones have been launched. In the near future, facsimiles and data communications in mobile devices will develop, and it is expected that facsimiles and printers using heat-sensitive recording media will be used even in automobiles.

上になることは、従来公知である。However, the thermal recording medium conventionally used as recording paper performs recording by heating, and is generally intended to be used indoors, so it is sensitive to heat. In a still-temperature atmosphere, there is a problem that it is easy to form. In other words, the heat-sensitive = R2 recording medium has a characteristic that it starts to color at about 60°C, and if it is stored for a long time in an air temperature of 60°C or higher, the background will gradually develop color and the printing will be difficult. This not only degrades the quality but also makes the recorded surface unreadable. The temperature inside a car varies greatly depending on the season, weather, and region, but it is well known that if the car is parked for a long time under the scorching sun in summer, the temperature inside the car can easily rise to 60° C. or higher.

度が低くなってしまうと゛ぎう欠点がおった。A commonly used thermosensitive recording medium is also called a leuco thread thermosensitive recording medium, and its main components are a colorless or light-colored leuco dye, a color developer that develops color when the dye is dyed, and a heat enhancer to improve thermal sensitivity. A coloring layer consisting of a sensitizer, a pigment, and a binder that binds these together is provided on a base paper. Custom-made recording paper is determined by the type and composition of these material components, but recording paper with good heat sensitivity tends to fog up at high temperatures, and conversely, recording paper that does not fog up easily even at high temperatures has low heat sensitivity. When I put it away, it had a huge drawback.
従って、高温雰囲気で保存性、熱感度共にすぐれた感熱
記録媒体は得られていない。Therefore, a heat-sensitive recording medium with excellent storage stability and thermal sensitivity in a high-temperature atmosphere has not been obtained.

D<7 Hitherto, a thermosensitive recording medium like the one of the present invention has not been known. Next, the present invention will be explained in detail. In order to improve storage stability in a high-temperature atmosphere, it is essential to increase the melting or eutectic temperature of each material component. However, if the temperature is too high, thermal sensitivity will decrease. As a result of intensive studies on the materials and composition of thermal recording media, the present inventors found that the composition of the present invention does not cause ground fogging even in a high-temperature atmosphere such as the inside of a car during a storm, and has sufficient thermal sensitivity for practical use. It was discovered that a thermosensitive recording medium can be obtained, and the present invention was developed based on this discovery.

いる場合、熱感度は共融組成にるる時よりも低下する。The composition of a three-component system can be easily represented using a triangular diagram. Any composition within the triangular diagram can be represented by the composition on each side. For example, if the eutectic composition of the three components is X, the weight fraction of the leuco dye is XL on the side AB, the weight fraction of the color developer is XDl on the side BC, and the weight fraction of the heat sensitizer is X on CA
It is represented by D. When the composition is eutectic, when the composition is heated, all components become liquid when the eutectic temperature is reached. If the composition deviates from the eutectic composition, the eutectic composition
Even when the temperature becomes good, 7 parts of the material components remain unmelted. For this reason, @! When the composition of the eutectic medium deviates from the #C fusion composition, the thermal sensitivity is lower than when it has a eutectic composition.
