Abstract

The invention concerns an article comprising a nanolaminate coating, wherein the nanolaminate coating has a total thickness ranging from 20 to 500 nm and comprises at least one pair of layers constituted of adjacent first and second layers and a minimum of three layers, said first layer being an inorganic silica layer obtained by evaporation of silicon oxide, especially evaporation of SiO 2 , and the second layer being a silicon-based organic-inorganic layer obtained by deposition of an organosilicon compound or a mixture of organosilicon compounds under plasma or ionic assistance, and wherein the refractive index of the nanolaminate coating as a whole is lower than 1.58 at 550 nm.
