ABSTRACT:
This invention relates to a foil having an adhesion promoting layer overlying at least one side of said foil. The adhesion promoting layer is suitable for enhancing adhesion between the foil and another substrate. The adhesion promoting layer is derived from a composition comprising silanes (A) and (B).
Silane (A) is at least one compound represented by the formula ##STR1## wherein G.sup.1, G.sup.2, G.sup.3, G.sup.4, G.sup.5 and G.sup.6 are independently halogen, hydrocarbyloxy, or hydroxy groups; R.sup.1 is a hydrocarbon group or nitrogen-containing hydrocarbon group; and n is zero or 1.
Silane (B) is at least one compound represented by the formula ##STR2## wherein R.sup.2 is an organofunctional group, said organofunctional group being reactive with or having an affinity for said another substrate; and G.sup.7, G.sup.8 and G.sup.9 are independently halogen, hydrocarbyloxy, or hydroxy groups.
