  • Patent number: 4751167
    Abstract: An image producing material which consists essentially of a substrate, an image producing layer and a photosensitive layer in that order. Before the material is exposed to light, the adhesion between the image producing layer and the photosensitive layer is lower than that between the substrate and the image producing layer, whereas, upon exposure to light, the adhesion between the image producing layer and the photosensitive layer becomes higher than that between the substrate and the image producing layer, so that, after exposure, when the photosensitive layer is peeled off, the image producing layer in the exposed area is removed with the photosensitive layer, and the image producing layer in the unexposed area is left on the substrate. Thus, the image producing material enables an image to be produced simply by peeling off the photosensitive layer without the need to apply a special surface treatment to the image producing layer and without the need for any heat treatment or the like after exposure.
