Abstract:
1. A silicone resin that is represented by an average composition formula of Formula 1 and comprises a siloxane unit of Formula 2 and a siloxane unit of Formula 3, wherein a molar ratio of aryl groups bound to the silicon atom with respect to the total silicon atoms is in a range of 0.7 to 1.3, wherein a molar ratio of aryl groups bound to the silicon atom in the siloxane unit of Formula 2 with respect to the total silicon atoms is in a range from 0.4 to 0.8 and wherein a molar ratio of aryl groups bound to the silicon atom in the siloxane unit of the Formula 3 with respect to the total silicon atoms is in a range from 0.25 to 0.7: wherein the groups R in the Formula 1 R are substituents directly bound to a silicon atom, and each independently represents hydrogen, an alkoxy group having 1 to 12 carbon atom(s), a hydroxy group, an epoxy-containing group, a (meth)acryloyl-containing group, an isocyanate-containing group, an alkyl having 1 to 12 carbon atom(s), an alkenyl group having 2 to 12 carbon atoms, an aryl group having 6 to 18 carbon atoms or arylalkyl group having 6 to 19 carbon atoms; both of R
