Claim:
1. A glazing comprising a substrate having two main outer surfaces, at least one of which is a textured surface, consisting of a dielectric material having a refractive index n 1 , wherein: at least a part of the textured surface of the substrate is coated with a sol-gel layer consisting of a dielectric material having a refractive index n the absolute value of the difference in refractive index at 589 nm between constituent dielectric materials of the substrate and the sol-gel layer is less than or equal to 0.020, and wherein the part of the textured surface of the substrate comprising the sol-gel layer has a transmission haze of less than 5% and a lightness of greater than 93%.
