Patent number: 7291658Abstract: The present invention relates generally to radiation-curable ink formulations, and particularly, but not by way of limitation, to a family of radiation-curable ink formulations specifically for flexographic and screen printing applications. The inventive ink 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 Michael addition reactions.Type: GrantFiled: October 14, 2003Date of Patent: November 6, 2007Assignee: Ashland Licensing and Intellectual Property LLCInventors: Sridevi Narayan-Sarathy, Lisa M.
