Abstract
A composite sheet material includes a cover sheet, a substrate and an adhesion promoting layer. The cover sheet has a cover sheet material. The substrate has a substrate material. The adhesion promoting layer is disposed between the cover sheet and the substrate. A first side of the adhesion promoting layer disposed towards the cover sheet has an affinity to bond with the cover sheet material. A second side of the adhesion promoting layer disposed towards the substrate has an affinity to bond with the substrate material.
