Abstract: This specification discloses a method of producing decorated shaped articles from aluminium sheets involving the application of a decorative pattern to the sheet using a high temperature resistant synthetic rubber material as the etch resistant coating followed by spinning or otherwise shaping the metal sheet into the desired shape and etching the shaped sheet to partially remove metal in the regions not coated by the etch resistant material, and removing the etch resistant material from the article.
