ABSTRACT:
A coating composition useful in forming conductive layers comprises 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. Also disclosed is a preferred process for preparing a latex coating composition comprising 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.
