Abstract
A composition for a silicone resin containing a poly(methyl silsesquioxane) derivative having an alkoxysilyl group at an end of a molecule, and fine metal oxide particles having a reactive functional group on the surface thereof, wherein the composition further contains at least one compound selected from the group consisting of disilanol derivatives having silanol groups at both ends of a molecule and a monofunctional silane derivative represented by the formula (II): wherein X is an alkoxy group or a halogen atom. The silicone resin composition of the present invention can be suitably used as, for example, materials for encapsulating photosemiconductor elements for use in backlights for liquid crystal displays, traffic lights, outdoor big displays, advertisement sign boards, and the like.
