Abstract
The present invention relates to coating compositions containing oxidatively drying binders and anti-skinning agents corresponding to formula (Ia) or (Ib) ##STR1## wherein Y.sub.1 and Y.sub.2 are the same or different and represent hydrogen, chlorine or fluorine, X.sup..sym. represents a group corresponding to formula I ##STR2## and R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are the same or different and represent hydrogen, a C.sub.1 -C.sub.10 linear or branched alkyl group that may contain one or more hydroxy groups, an aryl group or a C.sub.5 -C.sub.7 cycloalkyl group. The present invention also relates to anti-skinning agent mixtures containing these anti-skinning agents.
