    摘要: This invention relates to a method of forming a substrate with preparing a surface capable of making a cocontinuous bond comprising the steps of 1) obtaining a copper or copper alloy substrate and 2) applying an etching composition which comprises (a) an acid, (b) an oxidizing agent, (c) a copper complexing agent, and (d) a copper complex, wherein the copper complex is present in an amount which precipitates when applied to the copper or copper alloy substrate. The method also includes the step of 3) treating the substrate with a coating composition and/or 4) applying a stripping composition to the substrate. The invention also relates to copper articles, having surface porosity, including multilayer articles such as printed circuit boards and compositions used in the method. The present invention provides microporous copper or copper alloy substrates which have improved adhesion properties to organic material.
