  • ADDITION-CURABLE SILICONE RESIN COMPOSITION, ADDITION-CURABLE SILICONE RESIN CURED PRODUCT, AND SEALED OPTICAL SEMICONDUCTOR ELEMENT
    Publication number: 20160194537
    Abstract: The present invention aims to provide an addition-curable silicone resin composition with excellent interfacial adhesion properties, storage stability, and transparency. The present invention also aims to provide an addition-curable silicone resin cured product formed from the addition-curable silicone resin composition and a sealed optical semiconductor element formed by using the addition-curable silicone resin composition. The present invention is an addition-curable silicone resin composition including: an addition-curable silicone resin mixture; and an adhesion-imparting agent, the addition-curable silicone resin mixture having a refractive index of 1.35 to 1.45, the adhesion-imparting agent including a compound that includes a structural unit represented by the formula (1-3) and/or a structural unit represented by the formula (1-4) between a structural unit represented by the formula (1-1) and a structural unit represented by the formula (1-2), the compound having a refractive index of 1.35 to 1.
