感熱記録材料に関する。DETAILED DESCRIPTION OF THE INVENTION (5) Field of Industrial Application The present invention relates to a heat-sensitive recording material, and relates to a heat-sensitive recording material whose color development is completely improved to 1%.
■）従来技術

剤とが瞬時反応し。(2) Conventional heat-sensitive recording materials generally have a heat-sensitive recording layer r composed of two main components: an electron-donating dye precursor, usually colorless or light-colored, and an electron-accepting color developer, on a support. The dye precursor and the color developer react instantaneously by heating with a thermal Ben-laser source or the like.

このような感熱記録材料は比較的簡単な装置で記録が得
られ、保守が容易であること。Such a heat-sensitive recording material allows recording to be obtained using a relatively simple device and is easy to maintain.

比に対応して感熱記録材料の高感度化が求められるよう
になってきた。It has the advantage of not producing noise, and is used in a wide range of fields, including measurement recorders, facsimile machines, printers, computer terminals, labels, and automatic ticket vending machines. Particularly in the field of facsimile, demand for heat-sensitive methods is rapidly increasing, and speeds are being increased to reduce transmission costs. In response to the high speed ratio of facsimiles, there has been a demand for higher sensitivity of heat-sensitive recording materials.

のである。Because high-speed facsimile machines can send and receive standard A4 documents in 10 to 20 seconds, the current that flows through the facsimile's thermal head is repeated over a very short period of time, less than a few milliseconds, and the heat energy generated by this is extremely short. The image is transmitted to the thermosensitive recording sheet and an image forming reaction τ is carried out.

も感熱記録材料を高感度化する１つの方法である。In order to perform an image forming reaction with fc thermal energy transmitted in a short time in this way, a thermosensitive recording material soaked in thermoresponsiveness must be
φ is required. In order to improve thermal responsiveness, it is necessary to improve the compatibility between the color developer and the dye precursor. A sensitizer is used for this purpose if necessary. When the sensitizer itself is melted by the transferred thermal energy, it has the function of dissolving or enclosing the nearby dye precursor and color developer in the bath and promoting the color development reaction7, so the thermal response of the sensitizer is One way to make heat-sensitive recording materials highly sensitive is to improve their compatibility with dye precursors and color developers.
