a metallized composite includes a thermoplastic sheet and at least one discontinuous layer of metal within the thermoplastic sheet . the discontinuous metal layer can be disposed between two thermoplastic layers that are bound together , such as by melting the layers together , pressing , or by use of an adhesive . the metallized composites of the invention can be employed as reflective surfaces , such as are used as mirrors or substitutes for chrome trim on automobiles . a particularly preferred metal as a component of the discontinuous layer of the composite is indium .
