PROBLEM TO BE SOLVED: To provide a low-cost high-molecular-weight photo-setting resin excellent in hardness, marring resistance and solvent resistance, while maintaining adherence and the like, and provide a resin composition containing the photo-setting resin, and a coating material containing the composition. SOLUTION: The photo-setting resin is obtained by copolymerizing an unsaturated compound having one glycidyl group and one polymerizable unsaturated bond with an unsaturated compound having one polymerizable unsaturated bond to give a copolymer (I), subjecting the copolymer (I) to addition reaction with an unsaturated compound having one carboxy group and one polymerizable unsaturated bond to give an acrylic photo-setting resin (II), and reacting the resin (II) with an isocyanate containing a photo-functional group.
