摘要： 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.
摘要翻译：本发明的热敏记录材料含有捕获并含有水和/或甲醇的三（2-甲基-4-羟基-5-叔丁基苯基）丁烷作为储存性改进剂，并且具有显示最大X射线衍射的晶体结构，衍射角2θ处的X射线衍射峰; 根据使用具有Cu-Kα线的波长的X射线的X射线衍射测定，为6.58°。记录材料在非印刷部分中具有改善的耐热性，同时保持印刷部分的耐湿热性。本发明的热敏记录材料具有热敏记录层，其相对于热敏记录层优选含有0.1〜15质量％的三（2-甲基-4-羟基-5-叔丁基苯基）丁烷，记录层。捕获并包含在三（2-甲基-4-羟基-5-叔丁基苯基）丁烷中的水和/或甲醇的量优选为总计0.1至10质量％。
