| 摘要 |
A thermosensitive recording medium comprising a thermosensitive recording layer containing an electron-donating color forming substance, an electron-accepting substance, and a color developability-improving agent is disclosed, said color developability-improving agent being a solid solution composed of two or more compounds containing at least one color developability-improving compound and having a single intrinsic melting point of not less than room temperature, preferably 60 DEG C or higher. The recording medium exhibits well-balanced performance among color developing sensitivity, static color developability, image stability, and stability before recording. |
