A reversible thermosensitive recording material is disclosed, which comprises (i) a reversible thermosensitive recording layer which comprises as the main components a matrix resin and an organic low-molecular-weight material dispersed in the matrix resin, and (ii) a light reflection layer made of a metal thin film, which is preferably surface-treated to have a specular gloss of 70 to 250% in accordance with JIS Z8741 or a surface roughness of 0.5 to 10 .mu.m in terms of the ten-point average roughness defined in JIS B0601. This reversible thermosensitive recording material may further comprises a crystal-growth controlling agent in the reversible thermosensitive recording layer.
