PURPOSE:To efficiently form polymerized images in a short period of time and to obtain color images having decreased color fogging by having an intermediate layer consisting of a layer formable high-polymer material between a color material layer and a polymerized layer. CONSTITUTION:The layers of the image forming medium are constituted of a base 5, the color material layer 4, the intermediate layer 3, and the polymerized layer 2. The intermediate layer is formed of the high-polymer material capable of forming laminar films by dissolving this material in a solvent and applying the soln. on a base material, then evaporating away the solvent or extrusion coating the soln. by melting onto the base material. The intrusion of a thermally diffusive material from the color material layer to the polymerized layer, etc., is then prevented by this intermediate layer at the time of a coating state of respective layers at the time of production of the medium consisting of, for example, nitrocellulose, etc., and a heating stage at the time of full-surface exposing. The generation of the adverse influence by the light absorption of the thermally diffusive material, such as desensitization of the polymerizable compd. and decrease in curing rate, is obviated. The polymerized images are thus efficiently formed in the extremely short period of time and the color images having the extremely decreased color fogging are obtd. |
