Abstract
Use of N-substituted 2,2,6,6-tetraalkylpiperadine compounds, their acid addition salts or complexes with metal compounds, optionally together with further stabilizers, for stabilizing acid catalyzed stoving lacquers based on hot crosslinkable acrylic polyester or alkyd resins against the action of light, moisture and oxygen. The combination of an N-substituted 2,2,6,6-tetraalkylpiperidine compound with a UV absorber is particularly effective in stabilizing said lacquers.
