PURPOSE:To provide a thermal recording body which uses coloring system of metallic compound as a basis wherein coloring density is high, ground does not color, and preservative stability of the ground is excellent without deteriorating chemical resistance and stationery resistance. CONSTITUTION:In a thermal recording body, a thermal coloring layer is formed on a support body by utilizing coloring reaction of leuco dye and developer. In the thermal coloring layer, behenic acid iron which is insoluble in water, gallic acid stearylester, leuco dye, 4-hydroxy-4'-isopropoxy diphenylsulfone, pigment, wax, fluorescent dye, and blue dye are included. |
