Abstract
Metal plates, e.g., of magnesium, zinc or copper, suitable for chemical milling and etching operations to produce photoengraving plates, printed circuit boards, nameplates, etc., comprising a metal layer and, adhered thereto, a plastic film layer having a thickness substantially smaller than that of the metal layer. The resulting composite laminates have proved outstandingly useful in permitting the employment of thinner metal layers, thus resulting in lighter weight and less expensive plates, yet retaining the required resistance to the chemical milling or etching process without impairment of mechanical stability and other desirable properties of the plate.
