  • Patent number: 6803092
    Abstract: A composition for electrophoretic deposition of an insulating, protective coating. The composition comprises a cationic resin emulsion; and a curative mixed with the cationic resin emulsion. The composition after electrophoretic deposition and curing provides the protective coating that has a concentration of extractable ionic contaminants less than about 200 nanograms/cm2; and a concentration of labile components less than about 36,000 nanograms/cm2. A coating composition according to the present invention provides an article in the form of a flexible printed circuit, used as an interconnect, comprising a film substrate and a plurality of conductive traces adjacent to a surface of the film substrate to receive the insulating protective coating using electrophoretic deposition techniques.
