Reversible thermosensitive recording medium and image processing method

摘要

The present invention provides a reversible thermosensitive recording medium including:
a support, and
a reversible thermosensitive recording layer laid on the support, the recording layer containing a reversible thermosensitive composition,
wherein the reversible thermosensitive composition forms a relatively color-developed state and a colorless state depending on a difference in a heating temperature and/or a cooling rate after heating by the use of an electron-donating color-forming compound and an electron-accepting compound; a resin component contained in the reversible thermosensitive recording layer is a resin in which a polyol resin having a hydroxyl value within the range of 100 KOHmg/g to 250 KOHmg/g is crosslinked; and as the electron-accepting compound, a urea compound represented by the following General Formula (1) is used,
where "n" is an integer of 23 or greater.
