Transparent substrate provided on at least one of its faces with an antireflection coating A that is exposed to the external environment, wherein the antireflection coating consists of a single thin layer formed from at least two materials of different refractive indices, the composition of which thin layer is based on either SiOxNy or on SizTil-zO2 and varies continuously through its thickness.
Transparent substrate provided on a least one of its faces with an antireflection coating A, wherein the antireflection coating consists of a single thin layer formed from at least two materials of different refractive indices, the composition of which thin layer is based on SizTi1-zO2 where z varies in a strictly continuous manner through its thickness from 0 to 1.
