PROBLEM TO BE SOLVED: To provide a graft polymer having a polyorganosiloxane structure, which is excellent in chemical resistance, wear resistance, and adhesion, has a good photo-curing property, is stable over time, and exerts a good photo-curing property without heat treatment after photoirradiation, and a photopolymerizable resin composition produced using the same. SOLUTION: A polyorganosiloxane graft polymer is used, which is prepared by binding a polyorganosiloxane structural unit and a structural unit having a repeating unit having a polymerizable double bond in the side chain via a sulfur atom.
