摘要:
A multilayered reflective body which is thermoformable and capable of being fabricated into a number of parts while maintaining a uniform reflective appearance is provided. The reflective polymeric body is formed from at least two diverse polymeric materials which differ in refractive index and which are arranged in substantially parallel alternating layers. The polymeric body is reflective in appearance yet is transparent or, colored if a coloring agent is included, upon illumination from a back light source. The polymeric body has application in variety of areas such as in an automobile lighting lens which is reflective and thereby indiscernible yet transmissive upon exposure to a back light source. Additionally, various parts of consumer appliances, for example a refrigerator door, can be formed from the polymeric body.
