Abstract
An iridescent vehicle badge (and methods for making it) that includes a translucent, polymeric badge having a non-planar shape and comprising an interior and an exterior surface. Further, at least one of the surfaces of the badge comprises a plurality of diffraction gratings that are integral with the badge, each having a thickness from 250 nm to 1000 nm and a varying period from 50 nm to 5 microns. In some cases, the thickness can range from 500 nm to 750 nm. The period, in some cases, can vary within a set of discrete values in one or more portions of the at least one of the surfaces of the badge, e.g., from 150 nm to 400 nm.
