1. A two-component solvent-based coating composition comprising:
a component A comprising an autoxidizable resin comprising unsaturated fatty acids and a metal-ligand complex as drying catalyst, wherein the metal is manganese, vanadium or iron; and
a component B comprising a (meth)acrylate compound and a thiol compound, wherein the (meth)acrylate compound is a poly (meth)acryloyl functional ester of (meth)acrylic acid and a polyhydric alcohol or a poly (meth)acryloyl functional dimer of such ester;
wherein component B is free of drying catalyst;
wherein component A is free of a compound comprising a thiol group and of a compound comprising a (meth)acryloyl functional group;
wherein the coating composition is free of cobalt; and
wherein the molar ratio of thiol groups in the thiol compound to ethylenically unsaturated groups in the (meth)acrylate compound is in the range of from 0.01 to 0.10.
