The electrically-conductive layer includes a film-forming binder comprising the latex polymeric addition product of from 20 to 65 mol % of styrene, from 30 to 78 mol % of n-butyl methacrylate, and from 2 to 10 mol % of the sodium salt of 2-sulfoethyl methacrylate. and at least about 60 weight percent composite electrically conductive particles. The composite electrically-conductive particles have a layer of electrically-conductive metal-containing crystallites overlying a nonconductive substrate particle. The electrically-conductive layer is formed by dispersing the composite electrically-conductive particles using polymeric milling media having a mean particle size less than 350 .mu.m to form a colloidal dispersion, combining the colloidal dispersion with the film forming binder to form a mixture, coating the mixture onto the support and drying the mixture to form the electrically-conductive layer.

摘要： 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.
