PURPOSE:To maintain an image at high contrast and at the same time, make it clearly visible without any adverse effect of illumination light by providing a specific metal thin fiim layer on the rear of a thermally sensitive layer. CONSTITUTION:The subject material consists of a reversibie, thermally sensitive recorddng layer which is composed mainly of a resin material and an organic resistance molecular material dispersed in the resin material, and has transparency changing reversibly depending on temperature, and a metal thin fiim layer as a light reflection layer. The thin layer has a glossiness of 70 to 250% or a finely uneven surface with a surface roughness of 5 to 10mum. The thermally sensitive layer 1 is, for example, provided on one side of a support 2 (transparent film) and the light reflection layer 3 is provided on the other. Film 5 is bonded to the light reflection layer 3 using an adhesive layer 4 for protection of the layer 3 as another model. In addition, the thermally sensitive layer 1 and the light reflection layer 3 provided on each support 2, 5 are simply placed over the other us a therd model. |
