Abstract: 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 diffi-action angle 2¸ of 6.58° according to X-ray diffraction measurement using an X ray having a wavelength of a Cu-K± 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.

Abstract: PROBLEM TO BE SOLVED: To provide a heat-sensitive recording material such as heat-sensitive recording paper which has a color development reinforcing effect of a printing part, while possessing heat and humidity resistance of a printing part, and besides, an improved heat resistance of a non-printing part. SOLUTION: This heat-sensitive recording material contains a tris (2-methyl-4-hydroxy-5-t-butyl phenyl) butene, including water and/or methanol, as a keeping quality modifier. The above butene has a crystal structure showing a maximum diffraction X-ray peak at a diffraction angle 2θ=6.58° by diffraction X-ray measurement using X rays with a wavelength of Cu-Kα.
