a multilayer , metal / organic polymer composite , exhibiting high specular reflectivity even after substantial elongation , is provided by metallizing a layer of thermoplastic organic polymers such as polystyrene or polycarbonate film with a normally solid soft metal such as indium or an alloy of tin and cadmium . subsequently the multilayer composite or at least a portion thereof can be stretched or elongated by more than 10 percent in both the longitudinal and traverse directions without losing its initial specular reflectivity . articles fabricated of the multilayer composite may be structurally reinforced by casting an elastomeric or rigid foam polymer such as polyurethane into a cavity defined by the deposit . the multilayer composites are useful in the manufacture of reflective and decorative parts for automobiles and other vehicles of transportation , as well as high barrier packages for foods and electroconductive elements .
