Abstract 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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
96 words
A process for information recording comprising producing a fine jet of high solids liquid containing resin, modulating the charge density of the jet by applying an electric field in accordance with the information to be recorded, directing the jet of liquid to a recording medium to record said information, while said information is still in a tacky state applying a finely divided pigment under pressure of from 1 to 90 pounds per square inch for from 1 to 95 seconds to said recorded information, thereby binding said pigment to said resin and rendering said information opaque.
Claim 2
Dependent Claim
96 words
A process for information recording comprising producing a fine jet of high solids liquid containing resin, modulating the charge density of the jet by applying an electric field in accordance with the information to be recorded, directing the jet of liquid to a recording medium to record said information, while said information is still in a tacky state applying a finely divided pigment under pressure of from 1 to 90 pounds per square inch for from 1 to 95 seconds to said recorded information, thereby binding said pigment to said resin and rendering said information opaque.
Claim 3
Dependent Claim
12 words
The process of claim 1 wherein said finely divided pigment is sprayed.
