    摘要: A composition for providing acid resistance to copper surfaces in the production of multilayered printed circuit boards. The composition comprises an acid, an oxidizer, a five-membered heterocyclic compound and a thiophosphate or a phosphorous sulfide compound. In a preferred embodiment, the phosphorous compound is phosphorus pentasulfide. The composition is applied to a copper or copper alloy substrate and the copper substrate is thereafter bonded to a polymeric material.
