摘要：
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
