(57) [Problem] To provide a heat-sensitive recording material having excellent coloring property and dot reproducibility, and excellent in head matching property and chemical resistance. SOLUTION: An average particle diameter is 2 to 10 μm on a support. m, an intermediate layer containing non-foamable plastic hollow particles having a hollowness of 90% or more, a thermosensitive coloring layer mainly containing leuco dye and a developer, and a protective layer mainly containing pigment and resin are sequentially laminated. In the heat-sensitive recording material, the protective layer contains aluminum hydroxide as a pigment and zinc stearate as a lubricant, and the weight ratio to the resin is 75 to 125% by weight of aluminum hydroxide and 5 to 15% by weight of zinc stearate. % By weight. |
