ABSTRACT:
Non-metallic articles are sensitized for deposition of adherent metal from electroless metal solutions in contact therewith by treatment with a first medium including cuprous ions and stannous ions thereby absorbing on the surface in situ at least said cuprous ions; thereafter treating the surface with a second medium to decrease the solubility of the cuprous ions and/or simultaneously removing the excess; and simultaneously or subsequently, if necessary, treating the surface with one or more agents to transfer said cuprous ions into a catalytically-active state.
