Described is a process for producing pulverulent, antioxidant-comprising coating compositions, comprising providing an aqueous polymer dispersions comprising one or more antioxidants and a polymer obtained by radical polymerization ofa) N,N-diethylaminoethyl methacrylate, andb) at least one radically polymerizable compound selected from esters of α,β-ethylenically unsaturated mono- and dicarboxylic acids with C1-C8-alkanols,wherein the antioxidants are incorporated into the aqueous polymer dispersion in the form of a solution or of a dispersion, and spray processing the aqueous polymer dispersion to provide a powder form.
