Electrical laminates can be prepared from an epoxy resin composition which comprises: (A) at least one epoxy resin having an average of more than one epoxy group per molecule; (B) an oligomer having a terminal phenolic hydroxyl group, which oligomer results from the reaction of a glycidyl ether of a halogenated phenolic compound and a halogenated phenolic compound; and (C) at least one catalyst for catalyzing a reaction between Component (A) and Component (B).
