Patent ID: 8916654

Claim:
A curable composition comprising: a linear polysiloxane that comprises an alkenyl group bound to a silicon atom, and comprises siloxane units represented by the following Formulas 1 to 3, a mole number of the siloxane unit of Formula 1 being 1 to 5 times as large as a mole number of the siloxane unit of Formula 2, and a mole number of the siloxane unit of Formula 3 being 0.01 to 0.2 times as large as mole number of the sum of the siloxane units of Formulas 1 and 2; and a silicon compound containing a hydrogen atom bound to a silicon atom: R a R b SiO 2/2 [Formula 1] R c R d SiO 2/2 [Formula 2] R e R f SiO 2/2 [Formula 3] wherein R a and R b are each independently an aryl group having 6 to 25 carbon atoms, R f is hydrogen, an alkyl group having 1 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, a hydroxyl group, an epoxy group, an alkenyl group having 2 to 20 carbon atoms, or an aryl group having 6 to 25 carbon atoms, R c and R d are each independently an alkyl group having 1 to 20 carbon atoms, and R e is an alkenyl group having 2 to 20 carbon atoms.
