Abstract
A composite laminate makes it possible to obtain transparent layered elements with diffuse reflection that can be used in esthetic and/or antireflection glazings, or even in transparent projection screens. The composite laminate includes an organic polymeric support, a layer and a first transparent organic polymeric substrate. The dielectric layer is disposed between the support and the substrate. The dielectric layer has a refractive index greater than the refractive index of the first substrate. The adhesive energy between the dielectric layer and the support is less than the adhesive energy between the dielectric layer and the substrate.
