    摘要: Provided are a polyurethane polyurea resin composition that has high storage stability without a decrease in viscosity or turbidity over time and a printing ink that has high storage stability without a decrease in viscosity or coloration over time. The resin composition contains, as essential components, a polyurethane polyurea resin (A), a polyhydroxymonocarboxylic acid (B) having an acid value of 340 to 500 mg KOH/g and a hydroxyl value of 680 to 1,300 mg KOH/g, and at least one solvent selected from the group consisting of an ester solvent (C1) and an alcohol solvent (C2).
