摘要：
An epoxy resin composition is provided comprising a biphenol-type epoxy resin and a polyhydric phenol resin curing agent derived from a polyhydric phenol compound having 2 or more phenolic hydroxyl groups attached at adjacent positions on the aromatic ring. A cured product with excellent stability and strength at high temperatures can be obtained useful as adhesives, castings, sealing materials, moldings, and laminates.
