Abstract
The invention discloses a new electroless plating catalyst and a process of using the same for selective plating. The catalyst and process are especially adapted for formation of EMI shielding for electronic components. The electroless plating catalyst comprises particulates dispersed in a liquid film forming composition which particulates are coated with a hydrous oxide that is reduced to a catalytic metal in contact with an electroless plating solution.
