RADIATION-CURABLE COATINGS FOR WOOD SUBSTRATES FROM MULTIFUNCTIONAL ACRYLATE OLIGOMERS

摘要

The invention detailed herein comprises a family of radiation-curate a coati ng formulations specifically for wood substrates. These coating formulations ar e based on multifunctional acrylate resins formed by the reaction of acrylate monomers and oligomers with .szlig.-keto esters (e.g., acetoacetates), .szli g.- diketones (e.g., 2, 4-pentanedione), .szlig.-keto amides (e.g., acetoacetanilide, acetoacetamide), and/or other .szlig.-dicarbonyl compounds that can participate in the Michael addition reaction. These coating resins will cure under standard UV-cure conditions without the addition of traditional photoinitiators.
