摘要
An epoxy resin composition having exceptional stability which is useful in the preparation of electrical laminates comprises an epoxy resin such as the diglycidyl ether of bisphenol A, an organic solvent, a polyhydric phenolic hardener and an acid having a pKa at 25 DEG C. of less than 2.5 or an ester of anhydride of such acid. The epoxy resin composition can also contain a bisphenol or bisphenol derivative such as bisphenol A. In addition, an accelerator such as an alkyl substituted imidazole can also be added to the composition prior to its use as in the preparation of electrical laminates.
