摘要： An object achieved by the present invention is to provide an active energy ray-curable ink composition that has flexibility (stretch resistance) at a low temperature while maintaining blocking resistance at room temperature, forms a printed material with excellent flexibility, and also has excellent durability against stacking of printed materials. According to the present invention, the active energy ray-curable ink composition is a composition including 35% to 50% by mass of a monomer A represented by General Formula (1) with respect to a total amount of the composition, a monomer B having a polymerizable unsaturated double bond and a structure represented by General Formula (2), and at least one polyfunctional polymerizable compound selected from urethane (meth)acrylate or amino (meth)acrylate.

摘要： The present invention uses a urethane resin composition including a urethane resin (A), a multifunctional acrylate (B), and a solvent (C). The urethane resin (A) is a reaction product of a polyol (a1) and a polyisocyanate (a2). The polyol (a1) includes an alkylene diol (a1-1) having two or more polymerizable unsaturated groups and represented by general formula (1) or an oxyalkylene diol (a1-2) having two or more polymerizable unsaturated groups and represented by general formula (2) below. The proportion of polymerizable unsaturated bonds in the urethane resin composition is within a range of 3 to 9 mmol/g. The urethane resin composition is a urethane resin composition that can form a coating film having excellent hardness, scratch resistance, and flexibility. HO—R1—OH  (1) HO—R1O—R2—OR3—OH  (2)
