| abstract |
The invention relates to a coating agent, containing the following: 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-stability agents (L1) based on a UV absorber, e) one or more light stability agents (L2) based on sterically hindered amines and f) one or more organic solvents (D), 1.) the polyester (A) having an OH value of 80 to 200 mg KOH/g and an acid value < 10 mg KOH/g, 2.) the polyacrylate resins (B) having an OH value of 80 to 200 mg KOH/g and an acid value < 20 mg KOH/g, 3.) the light-stability agent (L2 based on sterically hindered amines being functionalised by amino ether and 4.) the quantity of the light stability agent (L1) in the coating agent being at least 3 wt. % in relation to the coating agent. |
