Abstract

The invention describes a multi-ply, self-adhesive and deep-drawable protective sheet, especially for the internal and external outfitting of automotive vehicles, consisting of a carrier sheet containing a thermoplastic synthetic resin based on an ethylene-propylene-diene terpolymer and/or an ethylene-propylene copolymer and a homo- and/or copolymer of propylene, small amounts of fillers and conventional additives; a pressure-sensitive adhesive layer based on an alkyl acrylate and/or methacrylate and/or a copolymerizable, ethylenically unsaturated monomer, such as acylic acid, and a cover layer of a unilaterally siliconized polyolefin film.
