Abstract

The present invention relates to an adhesion promoting layer which exhibits high temperature stability and high peel strengths when used in a multi-layer structure for a printed circuit board. More specifically, the present invention relates to a multi-layer structure, containing a prepreg layer wherein the prepreg layer is made from an epoxy resin and a non-amine curing agent; and an adhesion promoting layer comprising a nitrogen containing silane compound. The present invention also relates to a multi-layer structure containing a metal foil layer; an epoxy prepreg layer wherein the epoxy prepreg layer is made from an epoxy resin and a non-amine curing agent comprising at least one of an acid, an anhydride, an alkoxide, a phenoxide, a polymeric thiol and a phenol; and an adhesion promoting layer comprising a nitrogen containing silane compound, wherein the adhesion promoting layer is between the metal foil layer and the epoxy prepreg layer.
