  A thermal recording material of the invention contains, as a storability improver, tris(2-methyl-4-hydroxy-5-t-butylphenyl)butane trapping and containing water and/or methanol and having a crystal structure that shows a maximum X-ray diffraction peak at a diffraction angle 2θ of 6.58° according to X-ray diffraction measurement using an X ray having a wavelength of a Cu—Kα line. The recording material has improved heat resistance in non-printing sections while maintaining the moisture-and-heat resistance in printing sections. The thermal recording material of the invention has a thermal-recording layer that contains the tris(2-methyl-4-hydroxy-5-t-butylphenyl)butane in an amount of preferably 0.1 to 15% by mass with respect to the thermal-recording layer. The amount of the water and/or methanol trapped and contained in the tris(2-methyl-4-hydroxy-5-t-butylphenyl)butane is preferably 0.1 to 10% by mass in total.
