Abstract
The present invention relates to improved methods of coating donor members with waterbome coatings, wherein a resin, a pigment, and water are combined in proportions effective to provide a donor member precursor composition; the donor member precursor composition is subjected to high pressure communition to provide a donor member conductive coating composition; and the donor member coating composition is coated onto a substrate. The present method advantageously provides a donor member coating which is substantially free of air pockets or defects. In preferred embodiments the resin is a phenolic resin, preferably a waterborne phenolic resin, such as a phenol-formaldehyde resole, and in other preferred embodiments the pigment is selected from the group consisting of carbon black, graphite, magnetite, nigrosine, and combinations thereof.
