A thermal recording material comprises a support and a thermal recording layer formed thereon, the thermal recording layer containing an electron-donating dye precursor and an electron-receiving developer that causes said dye precursor to develop a color, wherein said thermal recording layer contains vapor-phase synthesis silica, preferably, the vapor-phase synthesis silica has a specific surface area, measured by a BET method, of 50 to 200 m2/g and further is doped with aluminum oxide, and the thermal recording layer further contains the above vapor-phase synthesis silica and a diphenyl sulfones-bridged type compound, and the thermal recording material is excellent in anti-sticking property and image stability. |
