1. A composite laminate comprising:
an organic polymeric support comprising an edge, a first main face and a second main face;
a dielectric layer comprising a first main face and a second main face;
a first transparent organic polymeric substrate comprising an edge, a first main face and a second main face;
wherein:
the first main face of the dielectric layer is in contact with the second main face of the first transparent polymeric organic substrate;
the second main face of the dielectric layer is in contact with the first main face of the organic polymeric support;
the dielectric layer has a refractive index greater than the refractive index of the first transparent organic polymeric substrate;
an adhesive energy between the second main face of the dielectric layer and the first main face of the organic polymeric support is less than an adhesive energy between the first main face of the dielectric layer and the second main face of the first transparent organic polymeric substrate to make it possible to transfer, by separation, the dielectric layer from the organic polymeric support to the first transparent organic polymeric substrate, and the second main face of the first transparent organic polymeric substrate is textured with a surface roughness between 1 μm and 1 mm and/or chemically functionalized with a layer of silicone, and/or the first main face of the organic polymeric support is textured with a surface roughness between 1 μm and 1 mm.
