ってきた。(B) Conventional heat-sensitive recording materials generally have a heat-sensitive recording layer on a support, the main components of which are an electron-donating, usually colorless or light-colored dye precursor and an electron-accepting developer. By heating with a head, a thermal pen, a laser beam, etc., the dye precursor and developer react instantaneously and a recorded image is obtained. etc. are disclosed. These heat-sensitive recording materials have the advantages of being relatively easy to record, easy to maintain, and do not generate noise, and are suitable for measurement recorders, facsimile machines, printers, and computer terminals. It is used in a wide range of fields, including automatic ticket vending machines, labels, and train tickets. 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 such increased speed of facsimile, there has been a demand for higher sensitivity of heat-sensitive recording materials.

である。Since high-speed facsimile machines can receive and send standard A4 documents in a few seconds to 20 seconds, the current that flows through the facsimile lj thermal head is repeated over a very short period of time, less than a few milliseconds, and the thermal energy generated by this is very short. is transmitted to a heat-sensitive recording sheet to cause an image-forming reaction.

熱記録材料を高感度化する１つの方法である。In order to carry out an image forming reaction using thermal energy transmitted in such a short time, it is necessary to use a heat-sensitive recording material with excellent thermal responsiveness. In order to increase the thermal reactivity, 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 melts due to the transferred thermal energy, it has the function of dissolving or enclosing the nearby dye precursor and color developer and promoting the coloring reaction. Improving the thermal responsiveness or the compatibility with dye precursors and color developers is one way to make heat-sensitive recording materials highly sensitive.
