PURPOSE:To expose color sheets of individual colors to light in the same condition with high sensitivity to reduce the occurrence of photographic fog in a non-image part by providing an intermediate layer which is not colored practically and can be dissolved or swollen by a developer between a color layer and an adhesive layer. CONSTITUTION:The color layer has an exposed image removed in accordance with a photosensitive layer by following development to form a color image, and a high polymer compound which has film formability and solvent solubility and can be dissolved or swollen by the developer is used as a binder constituting the color layer. According as the thickness of the color layer is thinner within an allowable range, the developing capacity is higher and the picture quality is better. Since the intermediate layer is not colored practically, namely, does not include coloring agents, there is not the fear that an adhesive is dispersed and transferred and is adsorbed to the adhesive layer and there is not the fear that the intermediate layer is completed adsorbed, and through the intermediate layer is not completely removed and remains partially, the picture is not affected because it has not a color density practically. |
