PROBLEM TO BE SOLVED: To provide a photocurable resin composition having excellent adhesiveness between a display section and a touch panel section, giving a cured product having small cure shrinkage and high transparency and dielectric constant, and preventing corrosion of a transparent conductive film on the surface of a touch panel section.SOLUTION: A photocurable resin composition comprises (A) 20 to 40 mass% of a (meth)acryloyl group-containing polyurethane obtained after polyoxyalkylene polyol and polyisocyanate are reacted to obtain a polyurethane having a hydroxy group or an isocyanate group and the polyurethane is then reacted with a compound having a hydroxy group or a (meth)acryloyl group or a compound having an isocyanate group and a (meth)acryloyl group, (B) 40 to 60 mass% of a hydroxy group-containing polyurethane obtained by reacting polyoxyalkylene polyol with polyisocyanate, (C) 10 to 30 mass% of a photopolymerizable monomer and (D) 0.2 to 2 mass% of a photoinitiator, where the acid value is 0 to 5 mgKOH/g. |
