Claim:
1. An adhesive promoter composition comprising: 1 to 30% by weight of at least one film-forming resin; 0.01 to 40% by weight of at least two aromatic polyisocyanates; 10 to 90% by weight of at least one solvent; 0.1 to 10% by weight of tris(3-(trimethoxysilyl)propyl) isocyanurate; and 0 to 20% by weight of filler, each weight based on the total weight of the adhesive promoter composition, wherein at least one film-forming resin is a polyester film-forming resin having (i) at least one hydroxyl group, which has been reacted with an isocyanate group of the aromatic polyisocyanate in the adhesive promoter composition, and (ii) a molecular weight in the range of 3000 to 100,000 g/mol and an average OH number in the range of 1 to 10 mg KOH/g, and at least one of the at least two aromatic polyisocyanates includes tris(p-isocyanatophenyl) thiophosphate.
