PROBLEM TO BE SOLVED: To provide an active energy ray-curable resin composition capable of forming a coated film excellent in scratch resistance and flexibility in a good balance when forming a cured coating film, further low in curl property of the coated film at the time of curing and also excellent in hardness and crack resistance.SOLUTION: There is provided an active energy ray-curable resin composition containing an urethane (meth)acrylate compound (A) obtained by reacting an isocyanate compound (a1) and a hydroxyl group-containing (meth)acrylate compound (a2) and an urethane(meth)acrylate compound (B) obtained by reacting an isocyanate compound (b1), a hydroxyl group-containing (meth)acrylate compound (b2) and a polyol compound (b3), where the isocyanate compound (a1) is a compound having an isocyanurate skeleton, the isocyanate compound (b1) is alicyclic structure-containing isocyanate, an ethylenically unsaturated group concentration of the urethane(meth)acrylate compound (A) is 3 mmol/g or more, the ethylenically unsaturated group concentration of the urethane(meth)acrylate compound (B) is less than 3 mmol/g and a percentage content of the urethane(meth)acrylate compound (A) and the urethane(meth)acrylate compound (B) (mass ratio) [(A)/(B)] is 1 or more. |
