Patent ID: 7781522

Claim:
A curable silicone composition comprising: (A) an organopolysiloxane represented by the siloxane unit formula (1) given below and having at least two univalent organic groups that contain epoxy groups and are free of aromatic rings: [R 1 3 SiO 1/2 ] a [R 2 2 SiO 2/2 ] b [R 3 SiO 3/2 ] c (1) where R 1 , R 2 , and R 3 are univalent organic groups, at least two of which are univalent organic groups which contain epoxy groups and are free of aromatic rings; more than 20 mole % of R 3 are aryl groups; a+b+c=1; on average, “a” satisfies the following condition: 0≦a≦0.8; on average, “b” satisfies the following condition: 0≦0.8; and, on average, “c” satisfies the following condition: 0.2≦c≦1.0; (B) an organopolysiloxane represented by the following formula (4): Z—(CH 3 ) 2 SiO(CH 3 ) 2 Si—Z (4) where Z is 3-(m-hydroxyphenyl)propyl group; and (C) a curing accelerator.
