The disclosed method comprises applying a transparent coating composition to a plastics substrate, the composition comprising 30% to 60% by weight of a nanoparticles (B), 15% to 40% by weight, of urethane (meth)acrylates (A1) having 3 to 5 (meth)/acrylate groups per molecule, 0% to less than 10% by weight of urethane (meth)acrylates (A2) having more than 5 (meth)/acrylate groups per molecule, 0% to less than 10% by weight of urethane (meth)acrylates (A3) having less than 3 (meth)/acrylate groups per molecule, 55% to 80% by weight of compounds (C1) having 4 (meth)/acrylate groups per molecule, 0% to 15% by weight of compounds (C2) having 2 (meth)/acrylate groups per molecule, and 0% to 15% by weight of compounds (C3) having 3 (meth)/acrylate groups per molecule, the sum of the weight fractions of film-forming components (A1), (A2), (A3), (C1), (C2), and (C3) being in each case 100% by weight.
