Abstract
An object is to constitute an active energy ray-curable flexographic printing ink composition that uses more biomass-derived components, while still maintaining such basic properties as curability, adhesion, rub resistance, scratch resistance, etc. As a solution, an active energy ray-curable flexographic printing ink composition is provided that contains a plant oil-modified polyfunctional (polyester) oligomer by 20.0 to 70.0% by mass in the ink composition and an acrylamide derivative by 20.0 to 45.0% by mass in the ink composition, and has a viscosity of 300 to 2,000 mPa·s.
