Curable silicone resin composition

Abstract

A curable silicone resin composition has excellent closed-system curability, adhesiveness, heat-resistant coloration stability, and balance between transparency and adhesive strength. The curable silicone resin composition is a curable silicone resin composition comprising 100 parts by mass of a silicone A, the weight-average molecular weight of which is 20,000 to 200,000, and which has 2 or more (meth)acryloyl groups per molecule; 10 parts by mass or more of a silicone B, the weight-average molecular weight of which is 1,000 or greater but less than 20,000, and which has 2 or more (meth)acryloyl groups per molecule; 2 parts by mass or more of a silicone C, the weight-average molecular weight of which is 300 or more but less than 1,000, the (meth)acrylic equivalent of which is less than 450 g/mol, and which has 2 or more (meth)acryloyl groups per molecule; and a radical initiator.
