Abstract
A water-based ink for non-permeable media includes: a pigment, a urethane resin, a polyethylene wax, triethylene glycol monobutyl ether, and water. The urethane resin has a glass transition temperature of 40° C. or more and 110° C. or less and a breaking elongation at 25° C. of 50% or less. The polyethylene wax has a melting point of 100° C. or more and 140° C. or less. The content of the urethane resin is 3 mass % or more and 8 mass % or less in terms of solid content. The content of the polyethylene wax is 2 mass % or more and 5 mass % or less in terms of solid content. The content of the triethylene glycol monobutyl ether is 3 mass % or more and 6 mass % or less.
