发明名称 Reflektierender polymerer Mehrschichtkörper
摘要 A multilayered reflective body comprises alternating layers of at least first and second polymeric materials of which layers a substantial majority have an optical thickness of not more than 0.09 micrometers or not less than 0.45 micrometers, and adjacent layers of said first and second polymeric materials differ from each other in refractive index by at least 0.03. A sufficient number of layers are present that essentially no perceived iridescence is reflected and, usually, 30 percent of non-absorbed incident light is reflected. The reflective body may be fabricated into sheets, mirrors, noncorroding metallic appearing articles and parts, reflectors, and reflective lenses.
