Abstract
Official abstract text for this publication.
The invention relates to a process for depositing an anti-fouling top coat onto the outermost coating layer of a coated optical article, comprising the following steps: a) providing an optical article having two main faces, at least one of which being coated with an outermost layer; b) treating said outermost layer with energetic species resulting in surface physical attack and/or chemical modification; and c) vacuum evaporating a liquid coating material for an anti-fouling top coat by means of an evaporation device, resulting in the deposition of the evaporated coating material onto the treated outermost layer of the optical article, wherein prior to the vacuum evaporation step of the liquid coating material, said liquid coating material has been treated with energetic species.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for depositing an anti-fouling top coat onto an outermost layer of an optical article, comprising the steps of: a) in an evacuatable vacuum chamber, providing both the optical article having two main faces, at least one of which being coated with the outermost layer, and a liquid antifouling coating material; then b) performing an activation treatment of said outermost layer with energetic species, which are chemical species or electrons, h…
