METHOD FOR IMPROVING THE EDGING OF AN OPTICAL ARTICLE BY PROVIDING A TEMPORARY LAYER OF AN ORGANIC MATERIAL

摘要

The invention relates to a method for edging an optical article comprising the following steps: providing an optical article having two main faces, at least one of which being coated with an outermost layer; fixing the optical article to a chuck by means of a holding pad, the surface of the holding pad to be contacted with the optical article being coated with an adhesive material; and edging the optical article; wherein prior the step of fixing the optical article to the chuck, at least one temporary protective layer of an organic material is formed onto said outermost layer of the optical article, the organic material of the temporary protective layer comprising at least one organic compound having a fluorinated functional moiety, and a linking functional moiety capable of establishing at least one intermolecular bond or interaction with the adhesive material of the holding pad.
