The present invention provides a reversible thermosensitive recording
medium including a support and a thermosensitive recording layer thereon,
in which the thermosensitive recording layer comprises an
electron-donating coloring compound and an electron-accepting compound,
and the thermosensitive recording layer is capable of forming a
relatively developed condition and a relatively erased condition
depending on at least one of the difference of heating temperatures and
the difference of cooling rates following to heating, and in which the
electron-accepting compound comprises a phenol compound represented by
the General Formula (1): ##STR00001## where, in the General Formula (1)
"l" represents an integer of 1 to 3, "m" represents an integer of 1 or
more, and "n" represents an integer of 7 or more.
