The invention relates to new reactive diluents of the formulae (Ia, Ib, Ic, Id, Ie) and to an alkyd coating composition comprising them. In a preferred embodiment R1 and R2 are hydrogen; R3 is (meth)acryloyloxy-methyl or phenyl para substituted by vinyl, R4 is phenyl or phenyl para substituted by vinyl or (meth)acryloyloxy; or a substituted phenyl residue of the formula -C6H4CH2-W , wherein W is (meth)acryloyloxy, or an aliphatic residue of the formula -CH2- Y- A, wherein Y is a bond, O-C1-C12alkylene, wherein the alkylene linker is linear or branched and may be interrupted once or more than once by oxygen, A is hydroxy, C1-C6alkoxy, acetoxy, (meth)acryloyloxy, or a phthalate- or maleate-residue; R5 is hydrogen; n is 1; X is -(CH2)-. The invention further relates to a solvent-based or water-based alkyd coating composition comprisi ng 0.3 to 10 wt. % of a mono-, bis- or trisacylphosphinoxide photoinitiator, especially Irgacure 819.
