(US5699188-A)      A metal-coated multilayer mirror comprises: (A) a multilayered polymer film in which the layers have an average thickness of not more than 0.5 micron; and (B) a metal layer comprising a reflective metal.    Also claimed is such a mirror in which (A) comprises (1) layers of a birefringent polymer having an average thickness of not more than 0.5 micron, and (2) layers of a selected second polymer having an average thickness of not more than 0.5 micron, wherein (A) has opt. been stretched in one direction(s) to at least twice that direction's unstretched dimension.    USE -   For solar reflectors, light pipes, fluorescent light reflectors, reflectors for back light in LCD's, back lights for computer displays, sign back lighting and retroreflective sheeting.    ADVANTAGE -   The mirror provides broad bandwidth reflection, high specularity, low mfg. costs, high reflectivity and high colour uniformity.    (EP835179-A1)      A metal-coated multilayer mirror comprises: (A) a multilayered polymer film in which the layers have an average thickness of not more than 0.5 micron; and (B) a metal layer comprising a reflective metal.    Also claimed is such a mirror in which (A) comprises (1) layers of a birefringent polymer having an average thickness of not more than 0.5 micron, and (2) layers of a selected second polymer having an average thickness of not more than 0.5 micron, wherein (A) has opt. been stretched in one direction(s) to at least twice that direction's unstretched dimension.    USE -   For solar reflectors, light pipes, fluorescent light reflectors, reflectors for back light in LCD's, back lights for computer displays, sign back lighting and retroreflective sheeting.    ADVANTAGE -   The mirror provides broad bandwidth reflection, high specularity, low mfg. costs, high reflectivity and high colour uniformity.
