PURPOSE:To provide a reversible thermal recording material excellent in printing/erasure repeated durability. CONSTITUTION:In a reversible thermal recording material wherein a thermal recording layer reversibly changed in transparency in dependence of temp. is provided on a support, the thermal recording layer is based on a resin matrix and particles of org. monomeric substances having relatively low and high melting points and characterized by that the content of particles of the low m.p. org. monomeric substance increases as approaching the support and the content of particles of the high m.p. monomeric substance decreases as separating from the support. |
