PROBLEM TO BE SOLVED: To obtain improved adhesive power by incorporating >=1 kinds of superfine metallic particles selected from Au, Pt, Pd, Rh, Ag, Ni, a binder consisting of an org. compd. contg. metals for fixing these particles and an org. solvent. SOLUTION: A high-polymer material, such a 'Nylon 11 (R)', is heated and melted under vacuum by a vacuum vapor deposition device and a vapor deposited high- polymer film is formed on a substrate. Next, >=1 kinds of the metals among Au, Pt, Pd, Rh, etc., are heated and melted under vacuum and the vapor deposited metallic films are formed on the high-polymer layers, by which the composite of the superfine metallic particles and the high polymer having a particle size of about 1 to 100m is produced. This composite is melted in a metacresol, etc., and is made into a paste form and thereafter, the binder, such as tetrabutoxy titanium, is added thereto at about 0.1 to 10mol per 1mol of the metals and a film reinforcing material, such as polysiloxane, at about 0.05 to 5mol and if necessary, a viscosity control agent, such as ethyl cellulose, by which the surface treating agent for plating is obtd. This treating agent is then applied on a base material and is fired at about 300 to 800 deg.C after drying, by which metal oxide is obtd. and the layers to be plated are formed. |
