Abstract:
1. A curable silicone resin composition, comprising: (A) a siloxane/polycyclic hydrocarbon-based compound containing at least 2 hydrogen atoms bonded to silicon atoms within each molecule, which is an addition reaction product of (a) a siloxane-based compound having at least 3 hydrogen atoms bonded to silicon atoms within each molecule, and (b) a polycyclic hydrocarbon having at least 2 addition reactive carbon-carbon double bonds within each molecule, (B) a siloxane-based compound containing at least 2 alkenyl groups bonded to silicon atoms within each molecule, and (C) a hydrosilylation reaction catalyst, wherein said siloxane/polycyclic hydrocarbon-based compound of the component (A) comprises at least one compound of the compounds represented by formula (1), formula (2) or formula (3) as follows:  wherein, X is a bivalent residue of said siloxane-based compound (a), Y is a bivalent residue of said polycyclic hydrocarbon (b), said Y moiety having one of the following structures: Y′ is a monovalent residue of said polycyclic hydrocarbon (b), said Y′ moiety having one of the following structures: H is hydrogen and p is an integer ranging from 0 to 1000;  wherein, X, Y and H are as defined above, and n is an integer ranging from 1 to 1000; and  wherein, X, Y and Y′ are as defined above, and q is an integer ranging from 1 to 1000;  wherein upon curing the cured silicone resin is colorless and transparent.
