ABSTRACT:
A method for the formation of novel colloidal catalytic electroless plating compositions comprises admixing a highly stable non-active colloidal dispersion with an activity modifier. The mixture so formed is used in electroless plating processes wherein a pre-cleaned substrate is contacted with the novel colloidal catalytic composition, rinsed, contacted with a reducing or activating solution and then contacted with an electroless plating solution.
