Resin composition, prepreg, laminate, metallic foil clad laminate, and printed circuit board

Abstract

An object of the present invention is to provide a resin composition that has a variety of properties required for a material for printed circuit boards such as high flame retardancy, and can attain a cured product having high moldability, high resistance against chemicals in a desmearing step, and a small coefficient of thermal expansion, a prepreg comprising the resin composition, a laminate including the prepreg, a metallic foil clad laminate including the prepreg, and a printed circuit board including the prepreg. A resin composition comprising an acrylic-silicone copolymer (A), a halogen-free epoxy resin (B), a cyanic acid ester compound (C) and/or a phenol resin (D), and an inorganic filler (E).
