THE FORMATION OF CONDUCTIVE METAL REGIONS ON SUBSTRATES

摘要

An activator composition for forming an activator-containing region on a substrate for activating a chemical reaction to form a conductive metal region on the substrate, the composition being suitable for thermal inkjet printing, the composition comprising a single phase aqueous composition including one or more curable materials and one or more co- solvents for the curable material(s); and an activator for reaction to form a conductive metal region. Conductive metal regions may be formed on the resulting activator-containing regions by a metallisation reaction such as electroless deposition.
