Abstract:
A reversible thermosensitive recording medium, comprising a supporting substrate and a reversible thermosensitive recording layer disposed on at least a part of said supporting substrate which comprises: a matrix resin and a low molecular weight organic material dispersed in said matrix resin, wherein said reversible thermosensitive recording layer turns a first color at a first temperature and a second color at a second temperature higher than the first temperature, and remains at the second color after cooling, wherein the reversible thermosensitive recording medium has a rate of change in recording sensitivity of 50% or less and in erasure sensitivity of 80% or more and has an average maximum particle size of 2.5 microns or less, wherein said low molecular weight organic material is a mixture of at least one low melting point, low molecular weight organic compound with at least one high melting point, low molecular weight organic compound, and neither type of organic compound has a carboxyl group therein.
