Patent attributes
A layer of material that binds to the next material to be printed is applied. In an embodiment this material is a resin containing a porous silica. The number of printing passes and amount of liquid accumulation is reduced by selecting ingredients of the ink to act both as a humectant and as a layer former, which permits the ink to have high amounts of active ingredient. In an implementation, two materials, the first an ink depositing amine and the second an ink depositing epoxy, are printed separately. They react in situ to form a single, dielectric layer. When the lower layer is a conductive metal trace or a wiring crossover on, for example, a paper substrate, a second metal trace perpendicular to the lower trace may be formed on the dielectric layer to form a capacitive circuit configuration.
