Ink compositions suitable for ink jet printing on metal, plastic, or paper surfaces, the ink characterized by opaque and visible properties in light, incorporating, in solution, a resin component, and at least one solvent, proportioned to give the ink as deposited a high degree of tackiness. The printing bears an overlying coating of at least one pigment. According to another of its aspects, this invention is a process for information recording comprising producing a fine jet of liquid, directing the jet of liquid onto a recording medium while modulating the density of the applied jet by an electric field in accordance with the information to be recorded, thereby recording said information, affixing pigments to said recorded information, thereby rendering said information opaque and visible. |
