Abstract

The use of 2,2,6,6-tetraalkylpiperidine compounds or their acid addition salts or complexes with metal compounds, if desired together with further stabilizers, for stabilizing two-layer uni-lacquer coatings based on thermocrosslinkable acrylic, alkyd or polyester resins, which if desired can be crosslinked with melamine/formaldehyde resins, epoxide resins or polyisocyanates, against the action of light, humidity and oxygen. The stabilization indicated in this specification is particularly suitable for lacquer coatings on cars.
