Abstract: Disclosed are functional polyallophanate oligomers comprising ethylenically unsaturated groups and polymer stabilizer groups selected from hindered amine light stabilizers, ultraviolet light absorbers, antioxidants and dihydrocarbylhydroxylamines. The ethylenically unsaturated groups and the polymer stabilizer groups are bound to the polyallophanate oligomers through allophanate and/or carbamate groups. The polyallophanate oligomers are useful in curable coatings, inks and varnishes. The present polyallophanate oligomers are derived from a) organic polyisocyanates, b) compounds containing at least one isocyanate reactive group and at least one ethylenically unsaturated group and c) polymer stabilizers containing at least one isocyanate reactive group.
