Claim Text:
1. A curable composition, comprising: (A) a linear or partially-crosslinked polyorganosiloxane having an aliphatic unsaturated bond; (B) a mixture of a first crosslinked polyorganosiloxane having an aliphatic unsaturated bond and a molar ratio (Ar/Si) of aryl (Ar) groups to total silicon (Si) atoms of 0.3 or less and having an average empirical formula of Formula 1, and a second crosslinked polyorganosiloxane having an aliphatic unsaturated bond and a molar ratio (Ar/Si) of aryl (Ar) groups to total silicon (Si) atoms of 0.3 or more, which is different from that of the first crosslinked polyorganosiloxane; and (C) a polyorganosiloxane including a hydrogen atom and an aryl group, which bind to a silicon atom, having a molar ratio of aryl (Ar) groups to silicon (Si) atoms of 0.3 or more, and including 3 to 10 silicon atoms: where R
