摘要
The invention describes a transparent foil composed of plastic with improved weathering resistance and increased intrinsic stability where the foil encompasses a) poly(meth)acrylate and polyvinylidene fluoride in a ratio of from 1:0.01 to 1:1 (w/w); and b) a mixture composed of UV stabilizers and of UV absorbers. PMMA matrix plastics with high molecular weights and with a certain selected coacrylate proportion are preferably used in order to achieve excellent weathering resistance, and also improved intrinsic stability of the surface-protection foils.
