| 摘要 |
<p>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 lithographic printing applications. The inventive ink formulations are based on multifunctional acrylate resins formed by the reaction of acrylate monomers and oligomers with beta-keto esters (e.g., acetoacetates), beta-diketones (e.g., 2,4-pentanedione), beta-keto amides (e.g., acetoacetanilide, acetoacetamide), and/or other beta-dicarbonyl compounds that can participate in Michael addition reactions.</p> |
