A photosensitive sheet comprising a sheet-shaped substrate, one surface of which is coated with a light-reflective substance or which is made of a light-reflective substance, and pressure-rupturable capsules that coat the light-reflective surface of the substrate or the other surface of the substrate, the pressure-rupturable capsules containing chromogenic materials and photosensitive materials that are hardened when illustrated with light, and a method for the formation of images using the said photosensitive sheet.

Photosensitive sheet and a method for the formation of images using the

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.

Image forming method combining heat and pressure to produce a color image

A photosensitive body for electrophotography has as its principal constituent a photoconductive layer having amorphous silicon with hydrogen, a surface layer having a greater optical band gap than the photoconductive layer formed on a photoconductive base member, and an intermediate layer sandwiched therebetween.

Photosensitive body for electrophotography containing amorphous silicon

A sheet-exposure stand supporting a photosensitive sheet on its sheet-placement surface, the photosensitive sheet being composed of a light-permeable substrate that is coated with pressure-rupturable capsules that contain chromogenic materials and photosensitive materials that are hardened when illuminated with light, and the sheet-placement surface being coated with or made of a light-reflective substance, and a method for the formation of images using the same.
