Abstract
A reversible thermosensitive recording medium including a substrate, and a thermosensitive layer including an electron donating coloring compound, an electron accepting compound, and a phenol anti-oxidation agent containing one or more sulfur atoms having an alkyl group on one side. In addition, the thermosensitive layer reversibly changes its color tone depending on temperature to reversibly record and erase an image thereon.
