PROBLEM TO BE SOLVED: To provide a reversible heat-sensitive composition in which an image can be formed and erased at a good contrast and the image can be agingly stably held in the environment of a daily life and a reversible heat-sensitive recording material using the same. SOLUTION: The reversible heat-sensitive recording material comprises a normally colorless or pale dye precursor and a reversible developer for bringing about a reversible color tone change in the dye precursor by the difference of cooling speeds after heating. The recording material comprises at least one type selected from a compound represented by formula (1) and at least one type selected from a compound represented by formula (2) as an achromatization accelerator. |
