Abstract: Process and device for producing two-colored or multicolored switchboard films, dashboard films or dashboards for motor vehicles produced therefrom using at least one backing film or backing layer, at least one upper film or upper layer which is arranged thereon and contains dyes and/or color pigments. The polymer melts for these films or layers come from two or more extruders and are supplied first to an adapter or a black box having at least one opening or a gap for the backing film or layer and at least one further opening for the upper film or upper layer. According to the invention, an adapter or a black box is used in which a wedge-shaped projection or a projection of triangular cross section is arranged. At least two different-colored polymer compositions in melt form, having identical viscosity or virtually identical viscosity (difference in MFI at 230.degree. C./2.16 kg of 0 to 0.

Abstract: The present invention relates to a deep-drawable film in the form of a laminated film which contains a top film having certain amounts by weight of (a) at least one crosslinked PP-EPDM and (b) one uncrosslinked propylene block copolymer or heterophase propylene block polymer, 15 to 1% by weight of (b) being replaced with the same amount by weight of a polymer and/or ionomer (c) containing reactive groups. The invention furthermore relates to the process for the production of the laminated film and the use thereof. The bottom film(s) contain(s) certain amounts by weight of (d) at least one partially crosslinked EPDM, (e) one propylene homopolymer, copolymer or graft polymer, (f) at least one polymer and/or ionomer containing reactive groups and (g) at least one polymeric crosslinking agent containing reactive groups.
