Abstract
An intaglio printing ink comprising a first binder compound selected from the group of water-soluble or water-thinnable acrylate oligomers, and optionally, a second monomeric binder compound selected from the group comprising water-soluble or water-thinnable PEG diacrylate or polyethoxylated polyol triacrylate monomers to adjust the viscosity of the ink composition. To initiate polymerization of the binder compounds upon irradiation by electromagnetic radiation or electron beam radiation a photoinitiator is included. Further optional additives, such as pigments, fillers, photosensitizers, stabilizers emulsifiers and security pigments may be present. The ink shows excellent wipeability and allows precipitation from the wiping solution.
