PROBLEM TO BE SOLVED: To provide a reversible thermal record medium having both high durability and visibility. SOLUTION: This record medium comprises a reversible thermal recording layer 4 wherein a transparent state and an opaque state are reversibly repeated by heating. The reversible thermal recording layer 4 contains a resin matrix formed of a resin A obtained by ester linkage of an acrylic acid or a metacrylic acid to a vinyl chloride/vinyl acetate/vinyl alcohol copolymer and an organic low-molecular substance, wherein the resin A is being cured. |
