Abstract: The purpose of the present invention is to provide a photocurable resin composition which exhibits excellent compatibility, drying properties when cured by irradiation with light, scratch resistance and adhesion to a substrate. The present invention is a photocurable resin composition containing a styrene-acrylate copolymer and an ethylenically unsaturated compound. The styrene-acrylate copolymer contains 10-90 mol % of constituent units (A) derived from a styrene-based compound and 10-90 mol % of constituent units (B) derived from an acrylate compound. The constituent units (B) derived from an acrylate compound contain constituent units (b-1) derived from a compound having at least three (meth)acryloyl groups in the molecule.
