ABSTRACT:
A photosensitive material is provided in which at least one surface portion of a substrate contains di-iodopropyl cellulose uniformly distributed therethrough. A photosensitive sheet material can be formed totally of di-iodopropyl cellulose or in part by di-iodopropyl cellulose, provided that the surface thereof contains di-iodopropyl cellulose. Upon exposure to electromagnetic radiation, including wave lengths not greater than 0.315 microns, radical iodine is liberated which forms molecular iodine spots to form an image corresponding to the intensity of the irradiation with the electromagnetic radiation. A provision is further made for bringing the surface of the material into contact with a substance which forms a colored compound upon reaction with the iodine.
