<p>Opaque ink compositions suitable for ink jet printing on metal, plastic, or paper surfaces, the ink characterized by opaque properties in light, incorporating, in solution at least one cellulosic derivative, a resin component, and at least one solvent, proportioned to give the ink property of opacity. According to another of its aspects, this invention is a process for information recording comprising producing a fine jet of liquid, directing said jet of liquid onto a recording medium, modulating the density of said applied jet by an electric field in accordance with the information to be recorded, thereby recording said information, and thereafter applying moisture to said recording medium bearing said recorded, thereby rendering said recording opaque.</p> |
