RESIN COMPOSITION, PREPREG, AND METAL FOIL-CLAD LAMINATE

There are provided a resin composition which exhibits high optical reflectance in an ultraviolet light region and a visible light region, undergoes less deterioration in optical reflectance when subjected to a heat treatment and a light irradiation treatment, has an excellent peel strength with a metal foil, and can be used suitably for an LED-mounting printed wiring board; a prepreg using the resin composition; and a metal foil-clad laminate using the resin composition, or the like. A resin composition of the present invention comprises at least an epoxy resin (A) having a bisphenol A skeleton, an alicyclic epoxy resin (B), an acid anhydride (C) of a completely or partially hydrogenated product of an aromatic polycarboxylic acid, titanium dioxide (D), and a dispersing agent (E).
