PROBLEM TO BE SOLVED: To manufacture a reversible thermorecording medium and provide a reversible thermorecording system for forming a color image of good visual recognition properties and clearness by heating. SOLUTION: A reversible thermorecording medium is constituted of a resin matrix 101 as a substrate, a color layer 102 with its surface formed on the resin matrix 101 and printing can be carried out thereon, a first reversible thermorecording layer 103 formed on the color layer 102, a first reversible heat color developing and reducing layer 104 formed on the first reversible thermorecording layer 103, a second reversible thermorecording layer 105 formed on the first reversible heat color developing and reducing layer 104, a second reversible heat color developing and reducing 106 formed on the second reversible thermorecording layer 105 and a third reversible heat color developing and reducing layer 107 formed on the second reversible heat color developing and reducing layer 106. |
