PROBLEM TO BE SOLVED: To provide a heat reversible recording medium, which has an enough erasability even under the condition that the heating time with a thermal head becomes shorter due to a quicker processing speed than ever, by which a high contrast picture can be obtained and with which a favorable repetition durability can be obtained without introducing valuable facilities. SOLUTION: In the heat reversible recording medium having a heat sensitive layer, the transparency of which changes reversibly in dependence with its temperature, the heat sensitive layer is made of organic low molecular substance particles dispersed in a resin matrix, and soft segments and rigid segments are provided between the resin functional groups constituting the resin matrix. |
