ABSTRACT:
An object with a homogeneous matted surface is provided which can be carried out in a simple manner and at low cost. The surface of the object has a thin skin layer produced by UV polymerization at a wavelength of at most 200 nm, and a core or carrier layer, beneath the skin layer, is produced by polymerization with UV radiation of a wavelength of at least 220 nm or by electron beams. A method for producing the matted surface is also provided, wherein a film made of an organic material that can be polymerized by UV radiation or electron beams is applied to a substrate; the film is irradiated with UV radiation of a wavelength of at most 200 nm, with the production of the skin layer at the surface, in which the organic material is at least partially polymerized; and the core area of the film, beneath the skin layer, is irradiated with UV radiation having a wavelength above 220 nm or by electron beams.
