The present invention provides an ultraviolet-curable organopolysiloxane, a composition containing the organopolysiloxane, and a cured product thereof, which is excellent in convenience and does not cause inhibition of surface curing even when cured in the atmosphere. The ultraviolet curable silicone composition is an organopolysiloxane represented by the following general formula (1), In the general formula (1), R 1 is each independently a monovalent hydrocarbon group having 1 to 10 carbon atoms or a group represented by the following general formula (2), and has at least one of the following general formulas in one molecule. A group represented by formula (2). m is a number satisfying 1≤m≤10000, In the general formula (2), R 2 is a group having at least one acryloyl group, methacryloyl group, acryloyloxyalkyl group or methacryloyloxyalkyl group, and R 3 is a group with 1 to 1 carbon atoms. 20 divalent hydrocarbon groups. |
