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.

用于制造一种光学物品的方法,该方法包括以下步骤:提供一个基底,该基底具有两个主面并且在其面的至少一个上携带‑OH官能团,在一个真空室中在导致将以下材料沉积到该基底的表面上的条件下按此顺序依次地将该携带‑OH官能团的基底的一个面暴露于至少三种不同的材料,被称为M1、M2、M3,以及任选地材料M4,并且其中:M1是一种取代的硅烷,包含:至少一个直接结合到该取代的硅烷的一个Si原子上的官能团X1,其中该Si‑X1基团能够与该基底的‑OH基团形成一个共价键,X1优选地是一个直接结合到该硅原子上的可水解基团(如–NH2基团)或‑OH基团并且包含至少一个含氟基团,M2是一种具有低于或等于900g/mol的数均分子量的取代的硅烷,包含:至少一个直接结合到所述取代的硅烷的一个硅原子上的官能团X2,其中该Si‑X2基团能够与该基底的‑OH基团形成一个共价键和/或与M1形成一个共价键,X2优选地是一个可水解基团(如–NH2基团)或‑OH基团以及至少一个疏水或疏油基团,或至少一个亲水基团,其中,M1具有大于M2的重均分子量并且M1与M2重均分子量之间的差值是等于或大于600g/mol,优选等于或大于900g/mol。M3是一种金属氟化物,任选的M4是一种非氟化的金属氧化物或金属氢氧化物。
