Patent ID: 8921496

Claim:
A curable composition comprising: a mixture of a linear polysiloxane and an siloxane oligomeric compound represented by the following Formula 3, the linear polysiloxane comprising an alkenyl group bound to a silicon atom and comprising siloxane units represented by the following Formulas 1 and 2, in which a mole number of the siloxane unit of Formula 1 is 1 to 5 times as large as that of the siloxane unit of Formula 2; and a silicon compound comprising a hydrogen atom bound to a silicon atom: wherein R a and R b are each independently 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, R 1 is an alkenyl group having 2 to 20 carbon atoms, R 2 is each independently an alkyl group having 1 to 20 carbon atoms, R 3 is an aryl group having 6 to 25 carbon atoms, R 4 is hydrogen, an alkyl group having 1 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, a hydroxyl group, a glycidyl group, an epoxyalkyl group, a glycidoxyalkyl group, an alicyclic epoxy group, an alkenyl group having 2 to 20 carbon atoms or an aryl group having 6 to 25 carbon atoms, and k is a positive number.
