ABSTRACT:
A multilayered, highly reflective polymeric body comprising at least two types of optical layers which is thermoformable and capable of being fabricated into films, sheets and a variety of parts while maintaining a uniform reflective appearance is provided. The reflective polymeric body includes at least first and second diverse polymeric materials having a sufficient number of layers of the first and second polymeric materials such that at least 30% of light incident on the body is reflected. A portion of the layers have optical thicknesses between 0.09 and 0.45 .mu.m, and the remaining layers have optical thicknesses of not greater than 0.09 .mu.m or not less than 0.45 .mu.m. The first and second polymeric materials differ from each other in refractive index by at least about 0.03.
