Summary:To provide a heat-sensitive recording material that is excellent in the water resistance and water plasticizer resistance of a recording part as well as the alcohol resistance of the recording part and a base part.SOLUTION: The present disclosure provides a heat-sensitive recording material which comprises, on a supporting body, a primer coating layer that contains an inorganic pigment, hollow particles, and an adhesive, and a heat-sensitive recording layer that contains a leuco dye, color developers, and an adhesive. The color developers include a first color developer and a second color developer. The second color developer is a compound represented by general formula (1) (where, R2 represents an alkyl group having 1 to 12 carbon atoms, an aralkyl group having 7 to 12 carbon atoms or an aryl group having 6 to 12 carbon atoms; the aralkyl group and the aryl group may be substituted with an alkyl group having 1 to 12 carbon atoms, an alkoxy group having 1 to 12 carbon atoms, an aryl group having 6 to 12 carbon atoms, or a halogen atom; the plurality of R2's may be the same as or different from each other; A1 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; and the plurality of A1's may be the same as or different from each other).SELECTED DRAWING: None 【課題】記録部の耐水性及び耐水可塑剤性、記録部及び地肌部の耐アルコール性に優れる感熱記録体の提供。【解決手段】支持体上に無機顔料、中空粒子、接着剤を含有する下塗り層、ロイコ染料、顕色剤、接着剤を含有する感熱記録層を有する感熱記録体において、前記顕色剤として第１顕色剤と第２顕色剤とを含有し、前記第２顕色剤として一般式（１）：TIFF2023154474000008.tif37170（式中、Ｒ２は、炭素数１～１２のアルキル基、炭素数７～１２のアラルキル基又は炭素数６～１２のアリール基を表し、前記アラルキル基及びアリール基は炭素数１～１２のアルキル基、炭素数１～１２のアルコキシ基、炭素数６～１２のアリール基若しくはハロゲン原子で置換されていてもよく、複数のＲ２は、同じであっても異なっていてもよい。Ａ１は、水素原子、又は炭素数１～４のアルキル基を表し、複数のＡ１は、同じであっても異なっていてもよい。）で表される化合物を含有ことを特徴とする感熱記録体。【選択図】なし
