Document Type and Number:
Japanese Patent JP7073815
Kind Code:
B2
Abstract:
To provide an active energy ray-curable resin composition capable of forming a coating film which has high transparency, good elongation characteristics, a high Young's modulus, and high strength when cured.SOLUTION: The active energy ray-curable resin composition contains: a urethane (meth)acrylate (A) being a reaction product of an alicyclic structure-containing polyvalent isocyanate (a1), a polyol (a2), and a hydroxyl group-containing (meth)acrylate (a3); and an ethylenically unsaturated monomer (B). The polyol (a2) contains a low-molecular-weight polyol (a2-1) having a number average molecular weight of 300 or less and a high-molecular-weight polycarbonate-based polyol (a2-2) having a number average molecular weight of 500 or more. The ethylenically unsaturated monomer (B) contains an ethylenically unsaturated monomer whose homopolymer has a glass transition temperature of 100°C or higher.SELECTED DRAWING: None
