A coating composition useful in forming conductive layers comprising a latex having water as a continuous phase and, as a dispersed phase, hydrophobic polymer particles having associated therewith a polyaniline salt semiconductor. The coating composition can be coated on a variety of supports to produce conductive elements. The coating compositions are particularly useful in forming antistatic layers for photographic elements or conducting layers for electrophotographic and electrographic elements. A preferred process for preparing a latex coating composition comprises the steps of loading polymer particles with the polyaniline component of the polyaniline acid addition salt semiconductor and then acidifying the latex to form a polyaniline salt coating composition.
