Abstract: The present invention relates to a process for the coating of polycarbonate substrates, in particular of transparent polycarbonate substrates, by applying a transparent coating composition encompassing at least one radiation-curing binder resin (A) and/or reactive diluent (C), nanoparticles (B), optionally solvent and at least one light stabilizer (L), to a polycarbonate substrate, wherein the coating composition comprises at least one light stabilizer (L) which comprises, per molecule, an average of at least one ethylenically unsaturated group bonded by way of a urethane group. The present invention also relates to the coating compositions used in said process, and to the coated polycarbonate substrates obtainable via the process, and to their use.
