description An aqueous, actinic radiation-curable coating composition containing a latex polymer emulsion and a multifunctional (meth)acrylate is disclosed. The critical aspect of the invention is that the actinic radiation-curable composition does not contain more than 5% by weight of the AOPAte ester of the multifunctional acrylate and 20% by weight of the ether resulting from a Michael addition of a multifunctional acrylate with the hydroxyl group of another multifunctional acrylate. This limitation on the maximum concentration of these components, which are typically the by-products formed in the manufacture of multifunctional (meth)acrylates, results in the improved appearance of the final cured coating.
