    摘要: A photo-curable composition having superior curability at room temperature and storage stability, and also offer a rubber-like cured product thereof having a good profile of properties including heat resistance, low-temperature performance, chemical resistance, solvent resistance and oil resistance. Specifically, A photo-curable composition which includes (A) 100 parts by mass of a linear polyfluoro compound having at least two alkenyl groups in a molecule and a linear perfluoropolyether structure in a backbone of the molecule, (B) a fluorine-containing organohydrogenpolysiloxane having at least two hydrogens bonded to a silicon atom in a molecule, and (C) 0.1 to 500 ppm of a photoactive hydrosililation catalyst relative to the mass of component (A) in terms of metal atom, wherein an amount of component (B) is 0.5 to 3.0 mol of Si—H groups in component (B) relative to 1.0 mol of alkenyl groups in component (A).
