Water-based composition for coating a donor member

摘要

A waterborne coating composition (10) for application to a donor member surface (15) includes a resin binder (30), a conductive particle material (40), an additional particle material (50) of either (1) graphite particles with a dispersant of polyacrylamide, polyethylene oxide, polyvinyl alcohol or mixtures thereof or (2) crosslinked polymer particles, and water. The waterborne coating composition (10) exhibits superior stability and achieves suitable properties when coated upon a donor member surface, thereby permitting practical replacement of volatile organic components typically used in donor member coating compositions.
