Method for obtaining anti-reflective surfaces.

摘要

A process for obtaining anti-reflective surfaces of mouldings is described, in which at least one single-ply film is used which is made of a thermoplastic material and has on at least one of its two surfaces regular structures which are raised 0.01 to 15 mu m, preferably 0.1 to 5.0 mu m, above the lowest regions of the respective surface and, if appropriate, are overlayed by statistically distributed, pointed individual elevations produced by inert particles incorporated into the film, the regular structures consisting of elementary cells of substantially uniform configuration which are arranged in the longitudinal and transverse direction and preferably connected to one another and whose average diameter dm = dmax + dmin DIVIDED 2 in which dmax = maximum diameter of the elementary cell at the widest point and dmin = minimum diameter of the elementary cell at the narrowest point is in the region of 10 to 800 mu m, preferably in the region of 20 to 400 mu m, and whose ratio of minimum to maximum diameter is in the region of 0.1
