The invention relates to a coating agent containing a) one or more polyester resins (A); b) one or more polyacrylate resins (B); c) one or more di- and/or polyisocyanates (C) with free or blocked isocyanate groups; d) one or more light stabilizers (L1) based on a UV absorber; e) one or more light stabilizers (L2) based on sterically hindered amines; and f) one or more organic solvents (D). The coating agent is characterized in that 1) the polyester (A) has a hydroxyl number of 80-200 mg KOH/g and an acid number <10mg KOH/g; 2) the polyacrylate resin (B) has a hydroxyl number of 80-200 mg KOH/g and an acid number <20 mg KOH/g; and 3) the light stabilizer (L2) based on sterically hindered amines is functionalized by aminoether.
