ABSTRACT:
A method for the formation of novel colloidal catalytic electroless plating compositions comprises admixing a highly stable non active (weakly active) colloidal dispersion with a reactivity modifier. The admixture so formed is used in electroless plating processes wherein a substrate is contacted with the novel colloidal catalytic composition, rinsed, contacted with a reducing or activating solution (which may be optional) and then contacted with an electroless plating solution.
