Patent ID: 8475619

Claim:
Process for improving the adhesion of a layer made of a material M to the surface of a substrate S, wherein the material M is a material that can be crosslinked by exposure to UV rays, and the process comprises: a) deposition, on at least one surface of the substrate S, of a nonpolymerized polymerizable composition P, comprising at least one molecule F comprising a first reactive group F 1 that is capable of reacting, by exposure to UV rays, with a reactive group M 1 of the surface of the material M, and a second reactive group F 2 that is capable of forming bonds with the material(s) constituting the surface of the substrate S, b) deposition, onto the layer of the nonpolymerized composition P obtained in step a), of a layer made of a noncrosslinked material M, and c) exposure to UV rays of the three-layer structure obtained in step b).
