[PROBLEMS] To form an ink layer having excellent adhesion, water resistance, solvent resistance, toughness, and bending resistance, and excellent active energy ray curing having excellent mixing property and printing processability even without solvent. To provide sex ink. The active energy ray-curable ink of the present invention comprises at least one resin (A) selected from an epoxy resin, an oxetane resin, and a vinyl ether resin, a polyol (B) having a number average molecular weight of 400 or more, and an active resin. A resin composition comprising an energy ray-sensitive catalyst (C), wherein the polyol (B) has a main chain comprising a carbon-carbon bond, a polyol (B1), a polycarbonate polyol (B2), a polyester polyol (B3), and a polyether It is characterized by being at least one polyol selected from polyols (B4).
