Abstract
Abstract The article comprises a polyimide layer and a layer of a metal benzotriazole above said polyimide layer wherein said metal is selected from the group of copper, silver, and gold, and a layer of metal adjoining said metal benzotriazole layer. The method for forming such an article comprises the steps: providing a layer of a metal benzotriazole adjoining a polyamic acid layer that may be a layer of a polyimide substrate being converted to polyamic acid, wherein said metal is selected from the group of copper, silver and gold; providing a layer of metal adjoining said layer of metal benzotriazole and converting said polyamic acid to polyimide.
