Abstract: The invention detailed herein comprises a family of radiation-curable coating formulations specifically for metal substrates. These coating formulations are based on multifunctional acrylate resins formed by the reaction of acrylate monomers and oligomers with ?-keto esters (e.g., acetoacetates), ?-diketones (e.g., 2,4-pentanedione), ?-keto amides (e.g., acetoacetanilide, acetoacetamide), and/or other ?-dicarbonyl compounds that can participate in the Michael addition reaction. An essential novelty of these coating resins is that they will cure under standard UV-cure conditions without the addition of traditional photoinitiators. Other materials, both reactive (conventional acrylates) and non-reactive (e.g., solvents) may also be incorporated into the resin oligomers to enhance the coatings properties on metal substrates.
