Abstract

Abstract Patterned electroless plating of aromatic polymeric organic substrate can be achieved by initially irradiating the surface of the plastic with patterned UV energy. The irradiated plastic can then be treated with a colloidal suspension of precious metal, such as palladium or an organo palladium compound. Activation of the applied precious metal provides patterned electroless deposition on the plastic surface when in contact with an electroless plating bath.
