EPOXY RESIN COMPOSITION, PREPREG AND LAMINATED BOARD

摘要

PROBLEM TO BE SOLVED: To provide an epoxy resin composition giving a cured product with excellent flame retardance even if no halogen compound is contained and with excellent in moisture absorption and adhesiveness, to provide a prepreg using the epoxy resin composition and a laminated board using the prepreg. SOLUTION: The epoxy resin composition comprises a phosphor-containing epoxy resin, an aromatic diamine and a solvent, wherein the phosphor-containing epoxy resin is obtained by modifying an epoxy resin with the phosphor compound (9,10-dihydro-9-oxa-10-phosphophenanthrene-10-oxide) represented by formula (1) and the aromatic diamine is a compound including 3-6 benzene rings in the molecule.
