Class Information
Number: 430/31
Name: Radiation imagery chemistry: process, composition, or product thereof > Electric or magnetic imagery, e.g., xerography, electrography, magnetography, etc., process, composition, or product
Description: Subject matter wherein the electrical conductivity of, the electrical charge on, the magnetic condition of, or the electrical emissivity of a medium is selectively altered by the action of electromagnetic radiation during imaging, and wherein a visible image is formed on the medium or latent image thereon which persists after imaging based upon difference in electrical or magnetic property described above; and when the visible or latent image is not formed by the action of electro-magnetic radiation, the image is finished as by development, fixing, transferring, or cleaning the surface, etc.; radiation-sensitive composition and product used in the process, process of making the composition and product, and finishing process, composition, and product used in the process.
