Abstract: The present invention relates to an aqueous radiation curable ink composition. The ink composition comprises: (a) an aqueous dispersion comprising anionic acrylated polyurethane and non-volatile cations; (b) at least one non-ionic or anionic surfactant; (c) at least one humectant selected from the group consisting of: polyol, polyether, polyether alcohol, polyether polyols, urea, and amide; and (d) water. The ink composition does not contain a water-soluble or water-miscible (meth)acrylate monomer. The ink composition is redispersible in water after drying and before curing, and the ink composition is water-resistant after curing by electron beam or actinic radiation.
