ABSTRACT:
A method for depositing a metal on a surface is disclosed. The method comprises coating the surface with a sensitizing solution comprising at least a reducible salt of a non-noble metal dissolved in a solvent comprising water and an alcohol having a total number of carbon atoms ranging from 2 to 8. The coated surface is treated to reduce the metal salt to metallic nuclei to form a catalytic layer thereon capable of directly catalyzing the deposition of a metal on said nuclei from an electroless metal deposition solution.
