A self-adhesive protective sheet for painted surfaces of vehicles, especially automobiles, whereinthe backing of the protective sheet is a film coated on one side with an adhesive and whose adhesion to steel is between 0.1 and 2.0 N/cm, andfollowing storage under alternating climatic conditions, the protective sheet can be removed without residue from painted surfaces at speeds of 20 m/min with a bond strength of from 2.3 to 3.6 N/cm, andthe protective sheet can be detached without residue following storage under alternating climatic conditions at a temperature of up to at least 50° C.,said adhesive comprising at least one polymer of at least two different alpha-olefins,no monomer having a fraction of 75 mol % or more in the polymer,the polymer having a Mooney viscosity ML (1+4) 125° C. of at least 50, andthe polymer likewise possibly including a diene as further comonomer.
