The invention relates to a transparent layered element having diffuse reflection properties and comprising two outer layers made from dielectric materials having essentially the same refractive index and a central layer inserted between the two outer layers and formed either by a single layer that is a dielectric layer having a refractive index different from that of the outer layers or a metal layer or by a stack of layers comprising at least one dielectric layer having a refractive index different from that of the outer layers or a metal layer. The upper outer layer is a sol-gel layer comprising an organic/inorganic hybrid matrix containing silica.
