PROBLEM TO BE SOLVED: To provide a heat-sensitive recording sheet of which the coloring property is favorable, and which does not generate unevenness on the surface even when being dipped in water or the like, and is excellent in preservation property such as heat-resistance, light-resistance and chemical-resistance. SOLUTION: On a supporting body, an under-coating layer, a heat-sensitive recording layer and a protective layer are laminated, and on the rear surface of the supporting body, a rear coating layer is provided for this heat-sensitive recording sheet. In this case, the major component of a binder of the heat- sensitive recording layer is a styrene-butadiene copolymer. A color-developer for the heat-sensitive recording layer is 2,4'-dihydroxydiphenylsulfone, and a sensitizer for the heat-sensitive recording layer is 2-(2'-hydroxy-5'-methylphenyl) benzotriazole. Then, the protective layer is a hydrophobic polymer. |
