Abstract
The present disclosure provides a silicone composition including: (a1) a first organopolysiloxane including a C2 to C20 alkenyl group bonded to at least one Si at both ends or a chain, the first organopolysiloxane formed from a unit represented by (R3SiO1/2)a(R2SiO2/2)b(RSiO3/2)c(SiO4/2)d (wherein a is in a range of 1 to 50, b is in a range of 100 to 500, c is in a range of 0 to 50, and d is in a range of 0 to 50); (a2) a second organopolysiloxane including a C2 to C20 alkenyl group bonded to at least one Si at both ends or a chain, and including at least one unit represented by SiO4/2; and (b) an organohydrogen siloxane comprising at least two SiH functional groups per molecule and comprising at least one C6 to C20 aryl group.

A silicone composition comprising:
- (a1) a first organopolysiloxane comprising a C2 to C20 alkenyl group bonded to at least one Si at both ends or a chain, the first organopolysiloxane formed from a unit represented by (R3SiO1/2)a(R2SiO2/2)b(RSiO3/2)c(SiO4/2)d (wherein a is in a range of 1 to 50, b is in a range of 100 to 500, c is in a range of 0 to 50, and d is in a range of 0 to 50);
- and
- (a2) a second organopolysiloxane comprising a C2 to C20 alkenyl group bonded to at least one Si at both ends or a chain, and comprising at least one unit represented by SiO4/2;
- and
- (b) an organohydrogen siloxane comprising at least two SiH functional groups per molecule and comprising at least one C6 to C20 aryl group,
