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).

Abstract: Provided is a flexible package laminate print ink composition including a pigment, a binder resin, and an organic solvent. The binder resin includes polyurethane resin including a biomass polyurethane resin obtained by a reaction of a biopolyester polyol component and an organic diisocyanate component, and includes, at a terminal thereof, a primary or secondary amino group. The biopolyester polyol component includes a dicarboxylic acid, a certain amount of organic acid having three or more active hydrogen groups, each having a certain molecular weight, and diol. At least one of the dicarboxylic acid and the diol is plant-derived, and has NCO group/OH group=1.2 to 3.0. A content of the biomass polyurethane resin in the polyurethane resin is 5 mass % to 100 mass %.
