Abstract
Provided is a conductive coating composition which comprises a colloidal dispersion of cuprous iodide particles in a binder resin solution which contains an ohmic bridging electrolyte. The preferred ohmic bridging electrolyte is potassium iodide. The colloidal dispersion also preferably exists in an aqueous system, with the binder resin being a water soluble polymer such as a polyvinyl alcohol. Upon coating a support with the dispersion, a transparent conductive coating is achieved comprised of ohmic bridged cuprous iodide particles and the binder resin. Such a coating composition can be advantageously used in the manufacture of imaging elements, and provides many advantages in the handling and manufacture of the imaging elements, as well as in the adhesive properties exhibited by the imaging elements.
