摘要
A method of making an iridescent, vehicular trim assembly is provided that includes: molding a polymeric base comprising an exterior surface; and over-molding an element over at least a portion of the exterior surface. The element comprises a polymeric, translucent material and an exterior surface with an integral diffraction grating having a thickness from 250 to 1000 nm and a period from 50 nanometers to 5 microns. Further, the molding can be conducted such that the polymeric base is molded with a tint. The method can also include forming a plated region over the exterior surface of the base. In addition, the method can also include cleaning the plated region with a plasma-etching process before the over-molding.
