PROBLEM TO BE SOLVED: To provide a practically useful repeating printing recording medium excellent in rewriting durability over many times, that is, excellent in heat resistance and mechanical strength, suppressing the lowering of the cloudiness of a recording part even after rewriting over many times and the lowering of the contrast of a recording part and a non-recording part and having a wide transparentizing temp. range erasing the recording part. SOLUTION: In a thermally rewritable repeating printing recording medium 10 wherein a thermal recording layer 2 and a protective layer 3 are successively laminated on at least one surface of a base material sheet, the thermal recording layer 2 consists of an org. monomeric substance and a curing agent and an org. monomeric substance is dispersed in the matrix polymer and the matrix polymer contains a resin having a reactive functional group capable of crosslinking with the curing agent. The protective layer is composed of a resin with elongation of 5-below 200%. |
