1. A polymerization method for the production of a matted surface on a substrate, which consists essentially of the following steps:

  • application of a film made of an organic material on the substrate;

    irradiation of the film with UV radiation of a wavelength of at most 200 nm, with the production of a thin skin layer, at the surface and in which the organic material is at least partially polymerized; and

    polymerization of a core area of the film, placed underneath the skin layer, by means of UV radiation of a wavelength of at least 220 nm or by means of electron beams, with the production of a carrier layer made of polymerized organic material, wherein the thin skin layer is polymerized before the core area is polymerized.
