Abstract
An aqueous composition for forming a micro-fluid jet printable dielectric film layer, methods for forming dielectric film layers, and dielectric film layers formed by the method. The aqueous composition includes from about 5 to about 20 percent by 65 weight of a polymeric binder emulsion, from about 10 to about 30 percent by weight of a humectant, from about 0 to about 3 percent by weight of a surfactant, and an aqueous carrier fluid. The aqueous composition has a viscosity ranging from about 2 to about 6 centipoise at a temperature of about 23° C.

A method of forming a dielectric layer, the method comprising the steps of:
- fluid jet printing onto a substrate a layer of an aqueous film forming composition comprising:
- from about 5 to about 20 percent by weight of a dispersion of a polymeric binder;
- from about 5 to about 30 percent by weight of a humectant;
- from about 0 to about 3 percent by weight of a surfactant;
- an aqueous carrier fluid,
- wherein the aqueous composition has a viscosity ranging from about 2 to about 6 centipoise at a temperature of about 23° C.;
- and
- heating the film forming composition layer to a temperature of about 80° to about 100° C. over a period of about 30 seconds to about 1 minute to form a cured layer;
- repeating the fluid jet printing and the heating one or more times on the cured layer to provide the dielectric layer.
