Claim:
A process for preventing skinning of an oxidatively drying paint or coating composition comprising: incorporating an anti-skinning agent, comprising an organic compound of formula (I) where R 1 and R 2 mutually independently represent hydrogen, a linear or branched, saturated or unsaturated C 1 -C 20 aliphatic radical, which can optionally be mono- or polysubstituted, or a C 6 -C 12 aryl radical, a C 7 -C 14 araliphatic radical or a C 5 -C 7 cycloaliphatic radical, and, an organic compound of formula (III) where R 5 represents hydrogen, a hydroxyl radical or a C 1 -C 7 alkoxy radical and R 6 represents hydrogen or an amine radical —NR 11 R 12 , R 11 and R 12 mutually independently represent hydrogen, C 1 -C 6 aliphatic radical, or C 5 -C 7 cycloaliphatic radical, or amine radical —NR 1 R 2 with the proviso that R 5 and R 6 are not simultaneously hydrogen, into the paint or coating composition.
