The invention relates to a method for producing molded plastic parts having functional surfaces. According to said method, a coating is produced on a support film, the coated support film is molded and is back- injected or back-foamed and the coating is allowed to cure or post-cure unless it has already done so. The coating is at least temporarily covered by a protective film that has a storage modulus E' of at least 107 Pa in the temperature range of from room temperature to 100 °C; it has an elongation at rupture of > 300 % at 23 °C lengthwise and transversally to the preferred direction generated during production of (S) using directional production methods; and, at a layer thickness of 50 mum, has a transmission of > 70 % for UV radiation and visible light having a wavelength of 230 to 600 nm. The side facing the coating has a hardness of < 0.06 GPa at 23 °C and a roughness, determined by atomic force microscopy (AFM) corresponding to an Ra value of 50 mum2 < 30 nm.
