International ClassB32B 009/00AbstractA lamellar polymeric body which may be reflective and which contains no metals and method of making it are provided. The body can be fabricated and/or post-formed into a variety of parts without alteration of its appearance. The body includes discontinuous layers of at least one polymeric material within a matrix of another polymeric material, which polymers differ in refractive index. The layers of the polymeric material may be either optically thick, optically thin, or optically very thin. | |
