Zusammenfassung:
(EN) Method for the manufacture of an optical article comprising the following steps: - providing a substrate having two main faces and bearing -OH functions on at least one of its faces, - successively exposing in this order one face of the substrate bearing OH functions to at least 3 distinct materials named M1, M2, M3 and optionally material M4 in a vacuum chamber under conditions resulting in the deposit of those materials on the surface of the substrate, and wherein: - M1 is a substituted silane comprising at least one function X1 directly bonded to a Si atom of the substituted silane, wherein the Si-X1 group is capable of forming a covalent bond with a OH group of the substrate, X1 being preferably a hydrolysable group (such a NH2 group) or a -OH group directly bonded to the silicon atom and comprising at least one fluorine containing group, - M2 is a substituted silane of number average molecular weight inferior or equal to 900 g/mol comprising at least one function X2 directly bonded to a silicon atom of said substituted silane wherein the Si-X2 group is capable of forming a covalent bond with a OH group of the substrate and/or a covalent bond with M1, X2 being preferably a hydrolysable group (such a NH2 group) or a OH group and at least one hydrophobic or oleophobic group, or at least one hydrophilic group, - Wherein M1 has a weight average molecular weight higher than M2 and the difference between M1 and M2 weight average molecular weights is equal to or higher than 600 g/mol, preferably equal to or higher than 900 g/mol. - M3 is a metal fluoride, - Optional M4 is a non fluorinated metal oxide or metal hydroxide.
