  • Printing ink composition for laminates and easily tearable laminate
    Patent number: 10577513
    Abstract: A printing ink composition for laminate contains a pigment, a binder resin, a polyfunctional isocyanate compound as curing agent, and an organic solvent, wherein the binder resin is a polyurethane resin and a vinyl chloride-vinyl acetate copolymer; at least one of the polyurethane resin and vinyl chloride-vinyl acetate copolymer has a reactive group that can react with the isocyanate group in the polyfunctional isocyanate compound; the ratio of the solid content of the polyurethane resin and that of the vinyl chloride-vinyl acetate copolymer is in a range of 9/1 to 1/9 (polyurethane resin/vinyl chloride-vinyl acetate copolymer); and the ratio of the sum of the solid contents of the polyurethane resin and vinyl chloride-vinyl acetate copolymer and the solid content of the curing agent is in a range of 1:0.2 to 0.9 ((polyurethane resin+copolymer):curing agent).
