Abstract

A multilayered reflective body 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 of a sufficient number of alternating layers of the first and second polymeric materials such that at least 30% of the light incident on the body is reflected. A substantial majority of the individual layers of the body have an optical thickness of not more than 0.09 micrometers or not less than 0.45 micrometers, with at least one of the individual layers having an optical thickness of not more than 0.09 micrometers, and adjacent layers of the first and second polymeric materials differ from each other in refractive index by at least about 0.03.
