    Abstract: The composition contains two different brominated epoxy polymeric components which are brominated diglycidyl ethers of bisphenol-A and epoxidized nonlinear novolak having at least about six terminal epoxy groups. The composition is suitable as impregnating agent in products comprising impregnated fibrous substrates. Such a product is for example the base material for printed circuit-boards. To produce such a board the fibrous substrate having the shape of a thin layer is impregnated with the composition. A multiplicity of such layers are laminated and cured. Finally a conductive material is laminated onto the cured structure.
