Reversible heat-sensitive recording medium

摘要

A reversible heat-sensitive recording medium comprising (i) a resin matrix, (ii) at least one organic low molecular weight material (A) which is at least partially insoluble in the resin matrix, exists in the resin matrix by phase separation and is dispersed as particles in the resin matrix, and (iii) an organic low molecular weight material (B) soluble in the resin matrix, wherein the organic low molecular weight material (B) can impart an orientation to the melt of the organic low molecular weight material (A) at a temperature of from T1 to T2 (wherein T1 is the melting point of the organic low molecular weight material (A) in the resin matrix, and T2 is the melting point of the organic low molecular weight material (B) in the resin material).
