(57) [Summary] [Problem] To provide good ink physical properties such as water resistance and adhesion. It can be used as a one-pack type ink, has excellent storage stability, and does not impair the re-solubility of the ink during printing, that is, printing suitability such as plate resistance of gravure ink. A water-based ink composition using a room-temperature-curable resin as a binder that can be used for the olefin-based film thus obtained. A polymerizable double bond-containing monomer containing at least one carbonyl group based on a keto group or an ald group in a molecule, and a polymerizable double bond-containing monomer copolymerizable therewith. An aqueous ink composition comprising a block of an aqueous didispersible resin copolymerized with an organic dihydrazide compound is used. |
