PURPOSE:To satisfactorily form a color copy from a visible light image, by combining a first sheet have a photosetting microcapsule containing achromatic leuco dyestuff and a photosensitive pigment, and a second sheet having a developer. CONSTITUTION:On a supporting body 11, a photosensitive layer 12 is provided and it becomes the first sheet 1. On its photosensitive layer 12, microcapsules C, M and Y are provided, and achromatic leuco dyestuff and a photosensitive pigment are contained therein. For instance, in the microcapsule C, a red photosensitive pigment and cyan coloring dyestuff are contained. Also, on a supporting body 21, a developing layer 22 is provided and it becomes the second sheet 2. Subsequently, white light 4 is allowed to pass through a full color original slide 3 and the first sheet 1 is exposed. At that time, each microcapsule is hardened by absorbing an intrinsic color light, and becomes an exposed sheet 1'. Next, the sheet 1' and 2 are laminated and pressed, the unhardened microcapsule is broken down, its contained object is shifted to the developing layer 22, and a positive color original image 22' is obtained. Accordingly, a full color image can be obtained by an exposure of once and a developing operation. |
