Abstract

A multilayer metal/organic polymer composite which has a formable thermoplastic polymer layer, a first metal layer adhered to the polymer layer and a second metal layer adhered to the first metal layer. The first metal layer is formed either from one metal or from an alloy of two or more metals. Suitable alloys are those which begin melting at a temperature within a range of from about 85 to 150 percent of the forming temperatures in degrees Kelvin of the polymer layer. If the first metal layer is formed from one metal, the metal is suitably, copper, silver, nickel or manganese. The second metal layer is a metal or an alloy of two or more metals that melts at a temperature which is less than that at which the first metal layer melts. The two metal layers, when taken together and heated to a specific temperature, comprise an alloy of two or more metals which melts at a temperature or over a range of temperatures within a temperature range of from about 80 to about 135 percent of the forming temperature in degrees Kelvin of the polymer layer. The multilayer composites have an optical density measurement of not less than 2.0 after being increased in area up to about 300 percent.
