A method for depositing a metal on a surface is disclosed. The method comprises treating the surface with a sensitizing solution comprising at least a reducible salt of a non-noble metal and a radiation-sensitive reducing agent for the salt to form a sensitized surface. The sensitized surface is exposed to a source of light radiation to reduce the metal salt to a reduced metal salt species. Either or both of the preceding sensitizing or radiation exposing steps is restricted to a selected pattern on the surface to form a catalytic real image capable of directly catalyzing the deposition of a metal thereon from an electroless metal deposition solution. The catalytic real image is treated with a stabilizer comprising (a) a reducing agent for the non-noble metal ions of said reducible salt, (b) a complexing agent and (c) an accelerator to at least stabilize the catalytic real image.
