<p>A metal (nickel, cobalt, copper or gold) layer if formed on the surface of a body of a polymer by degreasing the surface, forming on the degreased surface a film of a thermally decomposable palladium or platinum complex having the formula LmPdXn or LmPtXn, in which L is a ligand or unsaturated organic group; X is a halogen, an alkyl group or a bidentate ligand, m is an integer from 1 to 4 and n is zero or an integer from 1 to 3, heating the film on the surface to decompose the complex and leave, on the surface, a residue catalytic to an electroless metal-plating bath and then treating the catalysed surface with such a bath. When the polymer is polyethylene terephthalate or polypropylene, the complex is preferably bis-benzonitrile palladium dichloride; 1,3-butadiene palladium dichloride or bis-acetonitrile palladium dichloride and the film is heated at a temperature between 50 and 150.degree.C. When the polymer is polyethylene, the complex is preferably bis-benzonitrile palladium dichloride; 1,3butadiene palladium dichloride or bis-acetonitrile palladium dichloride and the film is heated at a temperature up to 98.degree.C When the polymer is a polyimide, the complex is preferably bis-trimethyl-phosphite palladium dichloride and the film is heated at a temperature up to 210.degree.C. The film of the complex is preferably formed by applying the complex in solution in a solvent which readily flashes off.</p> |
