    摘要: An epoxy resin composition useful in an electrical laminate, which composition comprises:(A) an epoxy resin prepared by reacting (A-1) an epoxy resin having an average of more than one, but less than three epoxy groups per molecule and (A-2) a phenolic compound having an average of more than one, but less than three hydroxyl groups per molecule at a ratio to provide an epoxy to phenolic equivalent ratio of 1:x;(B) y equivalent of a phenolic compound having an average of more than one, but less than three hydroxyl groups per molecule; and(C) at least one catalyst for catalyzing a reaction of Component (A) and Component (B);wherein x and y satisfy the following equations:x.gtoreq.0.01y.gtoreq.0.010.02.ltoreq.x+y
