Zusammenfassung:PROBLEM TO BE SOLVED: To provide a reversible thermosensitive recording material which is improved in printing durability of a protective layer and a reversible thermosensitive recording medium having flexural strength.SOLUTION: A reversible thermosensitive recording material 1 is a laminate which comprises: a reversible thermosensitive recording layer containing a reversible thermosensitive composition provided on a support; an anchor layer which is provided on the reversible thermosensitive recording layer and composed of a resin obtained by condensation of a compound having an isocyanate group and a compound having a hydroxyl group; and a protective layer composed of a resin provided on the anchor layer, wherein the compound having a hydroxyl group has a glass transition temperature of exceeding 40°C and 90°C or less and a hydroxyl value of less than 150 mgKOH/g and the anchor layer has a thickness of exceeding 0.2 μm and less than 2.5 μm. The reversible thermosensitive recording medium is obtained by laminating a substrate 2 on the support of the reversible thermosensitive recording material.
