Abstract:
A vehicle glazing includes on its surface to be exposed to the exterior atmosphere, at least in a zone not wiped by the windscreen wipers, a mineral oxide layer of 0.1 to 20 μm thickness, 30 to 90% of the volume of which consists of 20 to 300 nm open pores that are distributed uniformly throughout the thickness of the layer, and almost all of which are connected to one another, the internal and external surface of the layer being functionalized with a compound containing a perfluoroalkyl or alkyl functional group, then saturated with a hydrophobic oil that impregnates the functionalized porous layer and forms a film on the surface thereof, the at least one zone being located facing a detecting device such as an anti-collision/obstacle-detecting/security video camera, or similar, placed in the interior of the vehicle, in particular on the face of the glazing.

Claim (Index 8):
A process for manufacturing a glazing as claimed in  claim 1 , comprising in succession:\n depositing on a glazing substrate a liquid pore-forming agent composition and one or more mineral oxide precursors; calcinating the obtained assembly of the glazing substrate coated with the liquid pore-forming agent composition and the one or more mineral oxide precursors so as to remove the pore-forming agent and form a condensed porous layer on the substrate; grafting onto the external and internal surface of the porous layer a compound containing a perfluoroalkyl or alkyl functional group, then pouring an excess of hydrophobic oil onto the substrate, the substrate being held inclined in order to remove excess oil from the substrate.
