ABSTRACT:
Sensitizing solutions for rendering surfaces receptive to the deposition of adherent electroless metal comprising a precious metal and a stoichiometric excess of a Group IV metal which is capable of two valence states are stabilized against precious metal separation by adding a Lewis Base, e.g., hydroquinone or hydroxylamine. Processes for rendering surfaces receptive to the deposition of an electroless metal are also provided in which there are employed the stabilized sensitizing solutions.
