To provide a reversible thermosensitive recording medium comprising a
support, a thermosensitive recording layer formed on the support, and a
protective layer formed on the thermosensitive recording layer, wherein
the thermosensitive recording layer contains an electron donative
coloring compound and an electron acceptive compound, and the color tone
reversibly changes depending on the temperature, and the protective layer
contains a polymer of a composition containing two kinds of acrylate
compounds selected from an acrylate compound having a pentaerythritol
group and an acrylate compound having a dipentaerythritol group.
