THERMOSETTING RESIN COMPOSITION FOR LIGHT REFLECTION, PREPARATION METHOD THEREOF, REFLECTING PLATE FOR LOADING PHOTONIC SEMICONDUCTOR PREPARED THEREFROM, AND PHOTONIC SEMICONDUCTOR DEVICE CONTAINING SAME

摘要

The present invention relates to a thermosetting resin composition for light reflection, a preparation method thereof, a reflecting plate for loading a photonic semiconductor prepared therefrom, and a photonic semiconductor device containing the same. More specifically, the present invention relates to a thermosetting resin composition for light reflection comprising a polyvalent polyol containing two or more hydroxyl groups as a curing accelerator, wherein the light reflectance maintenance, represented by the following equation 1, of a sample prepared with the composition is about 70% or more, a preparation method thereof, a reflecting plate for loading a photonic semiconductor prepared therefrom, and a photonic semiconductor device containing the same.
