ABSTRACT:
A reversible thermosensitive recording medium is disclosed which includes an opaque support and a transparent recording film having a thermosensitive layer capable of reversibly assuming a maximum transparent state and a maximum opaque state depending upon the thermal hysteresis thereof. The recording film has an image display section in which a void space is provided between the recording film and the opaque support and a color discriminative from the color of the support. The display section in the maximum transparent state shows a reflectance greater by 5% than that in the maximum opaque state and a transmittance of 20-80% in the maximum transparent state, so that the visibility of the recorded image is improved.
