Abstract
Aqueous emulsions of epoxy resins, which can be used to treat glass cloth used in the preparation of printed circuit board laminates, are produced by combining an epoxy resin and a flame retardant phenol, such as tetrabromobisphenol A, with a selected nonionic surface active agent, such as an alkylaryl polyether alcohol, monomethylol dicyandiamide curing agent and, if needed, a catalyst.
