Abstract
Deposition of metal onto a polyimide film by an electroless method is disclosed. The subject method finds particular application in generating metal patterns on polyimide substrates, such as films. The subject method employs a photographic like technique for generating on a polyimide substrate, a pattern capable of attracting thereon a precious metal-salt which is useable as a catalyst in an electroless plating process. The methods disclosed are useable in an electroless plating process to produce a metallic pattern, such as an electric circuit pattern for mounting integrated circuit chips, etc.
