Abstract
A method of making an iridescent badge that includes: embossing a diffraction grating into a polymeric film to form a diffraction film; positioning the diffraction film in a mold; and injecting a translucent polymeric material into the mold over the diffraction film to form a vehicular badge. Further, the diffraction grating has a thickness from 250 nm to 1000 nm and a period from 50 nm to 5 microns. Another method of making an iridescent badge includes: heating a diffraction film positioned in a mold; applying a vacuum to form the film against a mold surface; and injecting a translucent polymeric material over the mold surface to form a vehicular badge. Further, the diffraction film comprises a polymeric material and a diffraction grating having a thickness from 250 nm to 1000 nm and a period from 50 nm to 5 microns.
