(A) Industrial Application Field The present invention relates to a highly sensitive heat-sensitive recording material with excellent thermal responsiveness. (B) Prior art A heat-sensitive recording material generally has 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 color developer. By heating with a head, thermal pen, laser light, etc., the dye precursor and developer react instantly.
This allows recorded images to be obtained, and is designated as Special Publication No. 43-4160.
It is disclosed in Japanese Patent Publication No. 14039/1983. Such heat-sensitive recording materials have the advantages of being able to record with relatively simple equipment, being easy to maintain, and producing no noise, and are suitable for measurement recorders, facsimile machines, printers, and computer terminals. ,
It is used in a wide range of fields such as labels, ticket vending machines, etc. Particularly in facsimile, the demand for heat-sensitive methods is increasing rapidly, 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. 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 thermal head is repeated over a very short period of time, less than a few milliseconds, and the thermal energy generated by this is extremely short. is transmitted to a heat-sensitive recording sheet to cause an image-forming reaction. 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 dissolves or encapsulates nearby dye precursors and color developers to promote the color reaction, so the thermal responsiveness of the sensitizer increases. Improving the compatibility with dye precursors and color developers is also one method for increasing the sensitivity of heat-sensitive recording materials. As such a method, waxes are used in JP-A-48-19231, JP-A-49-34842 and JP-A-Sho.

Publication No. 162379 discloses the addition of a benzoic acid ester derivative. However, the heat-sensitive recording materials produced using these methods are still unsatisfactory in terms of color density and color sensitivity. (C) Purpose of the Invention The present inventors investigated various sensitizers with the aim of obtaining a highly sensitive heat-sensitive recording material with further excellent thermal responsiveness. (D) Structure of the Invention In a heat-sensitive recording material containing a color developer that reacts with a normally colorless or light-colored dye precursor upon heating to cause the dye precursor to develop color, a compound represented by the following general formula is used as a sensitizer. By containing this, a highly sensitive heat-sensitive recording material with excellent thermal responsiveness could be obtained. general formula (However, X and Y represent hydrogen, halogen, a lower alkyl group, or a lower alkoxy group.) Specific examples of the compound represented by the above general formula include those shown below. The compound of the above general formula can be easily obtained by a known method. The sensitizer according to the present invention is usually added in an amount of 5% by weight or more based on the color developer. Preferred amounts are 10-400% by weight, particularly 20-300% by weight. If the amount added is less than 5% by weight, the effect of improving sensitivity will not be sufficient, and if the amount added is more than 400% by weight, it may be economically disadvantageous. The main components used in the heat-sensitive recording material of the present invention will be specifically explained below, but are not limited thereto. As a dye precursor, triphenylmethane type,

As the color developer, acidic substances generally used in thermal paper, ie, electron-accepting compounds, are used, and in particular, phenol derivatives and aromatic carboxylic acid derivatives are used.

After mixing these three types of dispersions, 125 g of a 40% dispersion of calcium carbonate was added, and 40 g of a 25% dispersion of zinc stearate and 285 g of a 10.5% polyvinyl alcohol aqueous solution were added, and the mixture was sufficiently stirred to form a coating solution. . The coating liquid was applied to a base paper having a basis weight of 55 g/m 2 so that the solid content coating amount was 6 g/m 2 , dried, and treated with a supercalender to obtain a heat-sensitive recording material.
