Thermosetting resin compositions

摘要

A thermosetting resin composition contains (A) a mixture of an imide compound having an allyl-free maleimide group and an imide compound having an allyl-containing imide group, (B) an epoxy resin, (C) a phenolic resin, and optionally, (D) an aromatic polymer/organo-polysiloxane copolymer. Component (B) and/or (C) includes a compound containing a naphthalene ring having a double bond conjugated with an aromatic ring. The composition is easily workable and well adhesive and cures to products having improved mechanical strength, hot-water resistance, low thermal expansion, and minimized water absorption.
