Curable liquids and inkjet inks for food packaging applications

摘要

A radiation curable liquid including at least one free radical polymerizable monomer or oligomer, at least one diffusion hindered acetalysation catalyst and at least one diffusion hindered hydroxyl containing compound. The radiation curable liquid applied to a substrate prevents migration of very low viscous monomers, such as vinyl ether acrylate monomers, into the substrate.
