Abstract
A method for image formation comprising the steps of exposing a light-receiving sheet coated with a layer of microcapsules containing photopolymerization agent and colorless dye selectively to light so as to form a cured image thereon opposite in sense to the desired final image, laying an image-receiving sheet uniformly coated with a layer of a developing material for reacting with and coloring the colorless dye on the light-receiving sheet, heating the resulting sandwich configuration and pressing these sheets against each other thereby rupturing the uncured microcapsules to form a colored image.
