Abstract
Image-forming light from a light source is projected to form a latent image with color information on a photosensitive sheet having a surface coated with microcapsules each containing a light-curable agent sensitive to light in a wavelength range corresponding to blue, green or red and a specified chromogenic agent which produces yellow, magenta or cyanic. An image transfer sheet with a surface coated with a developing agent having chromogenic effects on these encapsulated chromogenic agents is superposed on such a photosensitive sheet with a latent image formed thereon by selectively hardened microcapsules and these sheets are compressed together to rupture only those of the microcapsules which have not been hardened. The emission characteristics of the lamp used as the light source are such that the emission intensity is concentrated in wavelength ranges where the light-curable agents have peak photosensitivities.
