PROBLEM TO BE SOLVED: To provide a photocurable resin composition which gives a cured coating with high hardness that is hardly peeled on an acrylic resin film having poor adhesiveness without decreasing optical characteristics such as transparency, and which is suitable for forming a cured coating capable of preventing scratches or damages externally added.SOLUTION: The photocurable resin composition comprises: a polymerizable unsaturated group-containing monomer (A) having permeability (erosive property) to a specific acrylic resin film having poor adhesiveness; urethane acrylate (B) having a weight average molecular weight of 500 or more and a (meth)acryloyl group equivalent of 140 to 400 g/eq; and a reaction product (C) having a (meth)acryloyl equivalent of 250 to 800 g/eq, a hydroxyl value of 50 to 200 mgKOH/g and a weight average molecular weight of 5,000 to 30,000, which is obtained by adding and reacting a carboxyl group-containing (meth)acrylic compound (c2) to a polymer obtained by polymerizing a polymerizable component (c1) comprising an epoxy group-containing vinyl compound. |
