To provide a heat-sensitive recording material which is excellent in terms of high-speed printing performance among various performances required for heat-sensitive recording materials, and which is also excellent in terms of printing runnability, oil resistance, solvent barrier properties and the like.SOLUTION: A heat-sensitive recording material has a heat-sensitive recording layer on a supporting body, the heat-sensitive recording layer containing a colorless or pale electron-donating leuco dye and an electron-accepting color developer, while having a protective layer on the heat-sensitive recording layer. The heat-sensitive recording layer contains, as the electron-accepting color developer, at least one urea compound, and the protective layer contains an acrylic resin.SELECTED DRAWING: None 【課題】感熱記録体に求められる様々な性能のうち高速印字性に優れ、更に印字走行性、耐油性、溶剤バリア性等に優れる感熱記録体を提供する。【解決手段】支持体上に、無色ないし淡色の電子供与性ロイコ染料及び電子受容性顕色剤を含有する感熱記録層及び該感熱記録層上に保護層を有する感熱記録体において、該感熱記録層が、電子受容性顕色剤として、ウレア化合物を１種含有し、該保護層が、アクリル系樹脂を含有する、感熱記録体である。【選択図】なし
