Abstract

The invention relates to a method of producing on a transparent article, particularly a glass article, layers having a reflection degree of at least 10 percent on a first surface of the article and dereflecting layers on a second surface of the article. The method includes the steps of first by an immersion process providing both said surfaces with a dereflecting multiple-layered coating, and then providing said first surface with a single layer of a reflection increasing transparent coating.
