Abstract

The invention relates to the use of at least one compound from the tocopherol group for the color stabilization of ethylenically unsaturated monomers, particularly hydroxyalkyl(meth)acrylates, which already comprise at least one polymerization inhibitor for base stabilization or storage stabilization. Such color-stabilized and polymerization-inhibited monomers are preferably used in clearcoat and high solid paints.
