Abstract
An organic, top-surface, semiconducting dielectric overcoat, having a selected time constant permits electric field charge and dissipation at a selected rate to facilitate particulate material movement over an underlying electrode grid. The coating may be made from a compound including bisphenol A polycarbonate, or similar material, and a charge transport molecule (e.g. m-TBD). A planarized, wear resistant, chemically stable surface, with minimized inter-electrode build-up are also provided by the overcoat.
