Curable silicone composition

A curable silicone composition, comprising

• (A) a fluorocarbonsiloxane represented by the following general formula (1):
• ##STR46## wherein R.sup.1 and R.sup.2 each represent an unsubstituted or substituted monovalent hydrocarbon group, R.sup.3 represents a monovalent hydrocarbon group having 1 to 8 carbon atoms, Rf represents a bivalent group represented by the following general formula:
• ##STR47## wherein n is an integer of 0 to 8, m and l are each an integer of 0 to 5, and j and k are each an integer of 0 or 1, provided that l+m+n+j+k is an integer bringing the number of carbon atoms to 11 to 30, a is an integer of 2 to 300, b is an integer of 0 to 300, c is an integer of 0 to 5,000, p is an integer of 2 to 8, and X is a triorganosilyl group represented by the following formula:
• ##STR48## wherein R.sup.4 is an unsubstituted or substituted monovalent hydrocarbon group having an aliphatic unsaturated bond, and
• R.sup.5 and R.sup.6 each represent a monovalent hydrocarbon group having 1 to 8 carbon atoms,
• (B) an organohydrogensiloxane containing two or more Si--H groups in the molecule, and
• (C) a platinum family metal catalyst, the amount of the component (B) being such that the amount of the Si--H groups is 0.5 to 5.0 mol per mol of the aliphatic unsaturated group in the composition.
