| description | To provide a water-based ink for soft packaging capable of forming a coating film excellent in blocking resistance, adhesion to a substrate film, screen washing, and re-solubility.SOLUTION: A water-based ink for soft packaging comprises an aqueous resin (A) comprising an aqueous urethane resin (A1), and an alkalinity increasing agent (B). The aqueous urethane resin (A1) comprises an aqueous urethane resin (A11) whose 100% modulus when formed into a film is less than 8 MPa, and an aqueous urethane resin (A12) whose 100% modulus when formed into a film is more than or equal to 8 MPa. The 100% modulus when the aqueous urethane resin (A1) is formed into a film is less than 20 MPa. The glass transition temperature of the aqueous urethane resin (A1) is -30 to 130°C.SELECTED DRAWING: None
