Abstract
A reversible thermosensitive recording medium has a support, and a reversible thermosensitive recording layer, an intermediate layer and a protective layer which are successively overlaid on the support in this order, the recording layer containing a reversible thermosensitive coloring composition which includes an electron-donating coloring compound and an electron-accepting compound and is capable of assuming a colored state and/or a decolorized state by controlling the thermal energy applied to the coloring composition or the cooling rate of the coloring composition after the application of thermal energy thereto, and the intermediate layer and/or protective layer containing an inorganic pigment material with an average particle diameter of 100 nm or less.
