Abstract
A printed circuit is formed by a coating the entire region of at least one main surface of an insulating substrate with a resin type adhesive layer containing a solid solution consisting of titanium oxide, nickel oxide and antimony oxide, followed by selectively forming a mask on the adhesive layer to provide the non-masked region as a circuit-forming region. Further, the circuit-forming region is treated with a solution of an oxidizing agent and, then, subjected to an activation treatment. Finally, the mask is removed and a desired conductive layer pattern is formed on the activated surface region by means of electroless plating.
