Abstract
Disclosed is a conductive composition which can be used to form an aqueous conductive ink with increased conductivity. A film of the dry ink having a thickness of 5 microns or less has a surface roughness of less than 1.5 times the surface roughness of a cellulosic-based substrate which it coats. The aqueous conductive composition contains conductive particles, preferably silver, an anionic wetting agent and a styrene-acrylic copolymer. The composition is highly conductive and requires reduced drying energy. In addition, it may be applied to low cost substrates by high speed printing processes.
