Abstract
Abstract Catalytically inert films comprising complexes of polymer with a compound of a Group 1B or Group 8 metal at unusually low proportions of metal can be selectively activated, e.g. to provide a catalytic surface. Such films can be advantageously activatable to electroless deposition, e.g. of oxidation resistant layers of copper.
