摘要： The invention relates to a process for the manufacturing of an optical article comprising forming a multilayered coating on at least one face of an uncoated or coated substrate,and forming on the outermost layer of said multilayered coating, a layer-by-layer (LbL) coating exposed to environment, said LbL coating comprising at least two bilayers, each bilayer being formed successively by: i) applying a first layer composition comprising at least one compound A having a first electrical charge; ii) applying, directly onto the first layer resulting from i),a second layer composition comprising at least one compound B having a second electrical charge, said second electrical charge being opposite to said first electrical charge; iii) repeating at least once steps i) and ii), with the provisos that: -each of compounds A and B is independently chosen from polysaccharide polymers and colloids of metal oxide such as TiO2 and ZrO2 or silicon oxide, with the proviso that at least one of the compounds A and B is a polysaccharide polymer,—each of said compounds A and B is positively or negatively charged respectively, and d) crosslinking the first and second layers of said bilayers of the LbL coating by treatment with an aqueous composition comprising at least tetrakis(2-hydroxyethyl) orthosilicate (THEOS) as crosslinking agent to induce chemical linkages between compounds A and B. The invention also relates to the optical substrate obtained according to this process.
