Abstract (en)

[origin: WO2010034936A1] The present invention relates to a surface treatment method making it possible to confer upon the surface of a substrate antireflection properties with respect to electromagnetic radiation. A coating that is transparent with respect to said electromagnetic radiation is deposited on said surface and contains, in the scattered state within said layer, objects of less than 5 microns in size that include: - a core having a first refraction index nc, and a so-called skin layer, which surrounds the core and has a second refraction index nE separate from the refraction index nc of the core, where the ratio of the dimensions of the core to the dimensions of the core and the skin together is 1:1.5 to 1:5. The invention also relates to the coated substrates obtained according to said method.
