Abstract
A reversible thermosensitive recording material is composed of a support and a reversible thermosensitive recording layer formed thereon, which is capable of recording and erasing images repeatedly by utilizing its property that the transparency can be changed reversibly from a transparent state to an opaque state, and vice versa, depending upon the temperature thereof. The reversible thermosensitive recording layer is composed of a reversible thermosensitive layer and a protective layer formed thereon and has a scratching intensity of 10 g or more and a coefficient of friction of 0.10 or less. Images are reversibly formed and erased on this reversible thermosensitive recording material.
