Claim:
1. A process whereby a material obtained comprising a substrate of which at least a part of the surface of at least one of the faces of the substrate is based on organic compounds, the process being implemented at atmospheric pressure and without heating the totality of the said substrate, the process comprising the following stages: (a) in immediate proximity to the substrate, creating a region containing active species of a non-thermal plasma; (b) into said region injecting at least one precursor of a chemical element, the at least one precursor being selected from the group consisting of so as to deposit onto at least one face of the said substrate, at least one part of the surface being based on organic compounds, a first thin layer able to protect said substrate against oxidation reactions due to radicals; and (c) subsequently depositing a second thin layer with photocatalytic properties onto the first thin layer.
