Abstract

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 ss-keto esters (e.g., acetoacetates), ss-diketones (e.g., 2, 4-pentanedione), ss-keto amides (e.g., acetoacetanilide, acetoacetamide), and / or other ss-dicarbonyl compounds that can participate in Michael addition reactions.

Description

technical field

[0001] The present invention relates generally to radiation curable ink formulations and in particular, but not by way of limitation, to a class of radiation curable ink formulations particularly useful in offset printing and screen printing applications. Furthermore, the present invention relates particularly, but not by way of limitation, to a class of radiation curable ink formulations particularly useful in offset printing applications. The ink formulations of the present invention are based on multifunctional acrylate resins obtained by reacting acrylate monomers and oligomers with β-ketoesters (e.g. acetoacetate), β-diketones (e.g. 2,4- pentanedione), β-ketoamides (such as N-acetoacetanilide, acetoacetamide) and / or other β-dicarbonyl compounds that can participate in Michael (Michael) addition reaction to form.
