PURPOSE:To provide a resin compsn. which can improve hardness during heating without deteiorating adhesion and can give copper-clad laminates having excellent heat resistance and adhesion, consisting of a solid epoxy resin and a phenol novolak/epoxy resin. CONSTITUTION:An epoxy resin compsn. is obtd. by blending a solid epoxy resin (A) with a phenol novolak/epoxy resin (B) in a molar ratio of A:B=20-30: 80-70. When the compsn. is used for the production of copper-clad laminates, hardness during heating can be improved without deteriorating adhesion to copper foil. |
