RESIN COMPOSITION AND PREPREG AND METAL FOIL CLAD LAMINATE USING SAME

摘要

There are provided a resin composition which has 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 improved peel strength to a metal foil, has excellent heat resistance, and can be used suitably for an LED-mounting printed wiring board; and a prepreg and a metal foil-clad laminate using the same. The resin composition of the present invention comprises: an aliphatic epoxy-modified silicone compound (A); a multibranched imide resin (B) having an isocyanurate ring and a carboxyl group; titanium dioxide (C); and a dispersing agent (D).
