Abstract:
A reversible thermosensitive recording medium comprising, on a substrate, a reversible thermosensitive recording layer which comprises a matrix resin and an organic low-molecular-weight material dispersed in said matrix resin, of which transparency is reversibly changeable depending upon the temperature thereof, said organic low-molecular-weight material comprising a mixture of at least one straight chain hydrocarbon compound (A) comprising at least one bond selected from the group consisting of amide bond, urea bond and sulfonyl bond, and at least one carboxyl group, and having a melting point of 130.degree. C. or more, and at least one straight chain hydrocarbon compound (B) having a melting point which is lower by at least 30.degree. C. than the melting point of said straight chain hydrocarbon compound (A).
