Organic modified silicone resin composition

An organic modified silicone resin composition comprising:

• (A) an addition reaction product having two addition reactive carbon-carbon double bonds in one molecule, being a product of an addition reaction of
• (a) a compound shown by the following general formula (1), having two silicon atom-bonded hydrogen atoms in one molecule,
• wherein “R” independently represents an alkoxy group having 1 to 6 carbon atoms or a monovalent hydrocarbon group having 1 to 12 carbon atoms being unsubstituted or substituted with any of a halogen atom, a cyano group, or a glycidoxy group, and
• (b) a polycyclic hydrocarbon having two addition reactive carbon-carbon double bonds in one molecule;
• (B) a siloxane having a silicon atom-bonded hydrogen atom and an organic group substituted with an alkoxysilyl group, a siloxane having a silicon atom-bonded hydrogen atom and an organic group substituted with an epoxy group, or a combination thereof;
• (C) a compound having three or more silicon atom-bonded hydrogen atoms in one molecule other than the component (B);
• (D) a hydrosilylation reaction catalyst;
• and
• (E) fumed silica;
• wherein the formulation amount of the component (E) is 1 to 10 parts by mass relative to 100 parts by mass of the total amount of the components (A), (B), and (C);
• and
• having a viscosity of 15 to 50 Pa·s at 25° C., measured with a BH-type viscometer (10 rpm).
