銀めっき銅上の露出した銅の選択的コーティング

摘要

Silver-plated copper particles in which any exposed copper not plated with silver are coated with a polymer or with a chelating compound capable of preventing oxidation of the exposed copper. A method for preventing oxidation of any exposed copper on silver-plated copper particles and for improving the conductivity of silver-plated copper particles comprises coating a polymer or a copper-chelating compound onto the exposed copper on the silver-plated copper particles.
