Abstract
A method for creating patterned coatings on a molded article includes providing a molded article which has a surface comprising a first area and a second area, at least one surface property in the first area of the surface being different from that in the second area, applying a coating covering at least the first area and the second area to the surface of the molded article, the adhesion of said coating being greater in the first area than in the second area because of the at least one different surface property, and partially removing the coating by means of a removal process which is applied to the entire coating at a constant removal power that is determined such that the entire coating is removed in the second area while the coating remains in place on an entire surface of the first area.
