Patent No. EP3815838 (titled "Method For Producing A Transparent Part For A Vehicle") was filed by Compagnie Plastic Omnium on Nov 4, 2020. The application was issued on Jun 28, 2023.
A method for manufacturing a transparent vehicle part that improves aesthetic appearance by eliminating color matching issues with vehicle paint. The method involves applying a varnish layer to the transparent part, followed by a paint layer, and then laser etching the paint layer to achieve the desired opacity. This eliminates the need for an opacifying primer layer, which can cause color matching problems, and provides a precise and uniform appearance.
