摘要：
There is provided a reversible thermosensitive recording medium including a support, an intermediate layer, and a thermosensitive recording layer which reversibly changes a color thereof depending on a temperature, wherein the thermosensitive recording layer contains an electron-donating coloring compound, and an electron-accepting compound represented by the following general formula 1: where, n is an integer of 23 or more, and wherein the intermediate layer is disposed between the support and the thermosensitive recording layer, and contains hollow particles having a void ratio of 70% or more, a maximum diameter D100 of 5.0 μm to 10.0 μm, and a ratio D100/D50 of 2.0 to 3.0 where the ratio D100/D50 is a ratio of the maximum diameter D100 to a 50% cumulative particle diameter D50 of the hollow particles.
