A process for forming an abrasion-resistant antistatic layer for an imaging element comprises: adjusting the pH of an aqueous composition of an electronically-conductive polymer to a pH of about 3 to about 10, and combining the pH-adjusted aqueous composition of the electronically-conductive polymer with an aqueous composition at a pH greater than 7 of a polyurethane film-forming binder having a tensile elongation to break of at least 50% and a Young's modulus measured at 2% elongation of at least 50000 psi. The process further comprises applying the resulting coating composition to the imaging element, thereby forming an abrasion-resistant antistatic layer on the element. The antistatic layer coating composition of the present invention can be applied to a wide variety of imaging elements, including, for example, photographic, electrostatographic, photothermographic, migration, electrothermographic, dielectric recording and thermal-dye-transfer imaging elements.
