Abstract

Improved multi-layer composites are provided. The multi-layer composites include at least a first polymeric layer and a second polymeric layer formed over the first polymeric layer thereby forming an interface region there between. At least one of the polymeric layers is formed from a thermosetting composition which contains an adhesion promoter composition. The adhesion promoter composition is formed from (1) at least one adhesion promoting component, and (2) at least one surface active component. The improvement is represented by the presence of the adhesion promoting component (1) at the interface region.
