Abstract: A toner adder roll according to one example embodiment includes an electrically conductive shaft defining an axis of rotation of the toner adder roll. A foam member is cylindrically disposed about the shaft and forms an outer circumferential surface of the toner adder roll. The foam member is composed of a polymeric open-cell foam material. An abrasive agent is dispersed on the outer circumferential surface of the toner adder roll.

Abstract: The present invention provides an aqueous ink containing ?3% silver particles having much improved adhesion. It has been found that the adhesion can be improved by adding an aqueous cationic dispersion of a styrene/acrylate copolymer, PEI (polyethyleneimine), or arabinogalactan as an additive to the ink. The advantage of using one of these materials to improve the adhesion of the silver ink is the stability of the ink is maintained and the resistivity goal is met when printed onto the specified media. In other words, this invention provides a silver ink with great adhesion properties while still able to meet the <0.1 ?/square resistivity requirement and remain stable for up to 4 weeks at 60° C. at accelerated oven aging conditions.

Abstract: Printed circuits having conductive traces applied adjacent to a substrate, such as one where the traces have a resistivity of from about 1 to about 0.1 ohms/square, and methods for forming a fluid composition receiving layer adjacent to a substrate. One such method includes depositing a primary treatment fluid having a particle dispersion and a binder in a carrier fluid adjacent to at least a portion of a substrate to provide a treated substrate having a fluid composition receiving layer. The primary treatment fluid is deposited in a pattern using a: micro-fluid ejection head. After deposition, the carrier fluid content of the fluid composition receiving layer is reduced.
