ABSTRACT:
A metal-coated multilayer mirror having high reflectivity and high specularity. The mirror comprises a multilayered polymer film and a reflective metal layer. The multilayered polymer film preferably comprises layers of a crystalline, semi-crystalline, or liquid crystalline material, such as a naphthalene dicarboxylic acid polyester, having an average thickness of not more than 0.5 microns and layers of a second polymer having an average thickness of not more than 0.5 microns. Preferably, the layers of semi-crystalline naphthalene dicarboxylic acid polyester have a positive stress optical coefficient. The reflective metal layer comprises a metal selected from the group consisting of silver, gold, aluminum, nickel, copper, and titanium, with silver and aluminum being particularly preferred. The metal-coated multilayer mirrors are useful in applications requiring broad bandwidth reflection, high specularity, low manufacturing costs, and high reflectivity.
