Abstract

Disclosed is a conductive composition which can be used to form an aqueous conductive ink with increased conductivity. 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.
