ABSTRACT:
A process for the preparation of non-conductors prior to electroless metal plating with a catalyst composition. The catalyst formulation comprises the product resulting from the admixture of an acid, a nucleophillic reactant, stannous ions, a hydrolyzable stannic compound, and precious metal ions. The stannous ions are in a molar excess relative to either the stannic compound or the precious metal ions.
