Abstract
A photosensitive material is provided in which at least one surface portion of a substrate contains 2,3-di-(2,3-diiodopropoxy)-propyl cellulose uniformly distributed therethrough. A photosensitive sheet material can be formed totally of 2,3-di-(2,3-diiodopropoxy)-propyl cellulose or in part thereof, provided that the surface thereof contains 2,3-di-(2,3-diiodopropoxy)-propyl cellulose. Upon exposure to an activating electromagnetic radiation in which the intensity is modulated according to the configuration of an image, a visible image is formed on the surface of the material. Provision is further made for bringing the surface of the material into contact with the substance which forms a colored compound upon reaction with iodine liberated upon subjecting the surface to activating electromagnetic radiation.
