Optical article comprising a coating that is a precursor of an antifog coating having antifouling properties

摘要

The present invention relates to an optical article having a substrate coated with a coating that is a precursor of an antifog coating, the surface of which has a static contact angle with water larger than 90° and a polar surface energy component higher than 1.5 mJ/m². The precursor of the antifog coating, which furthermore possesses antifouling properties, is converted into an actual antifog coating by applying a surfactant film to its surface.
