摘要：
Solvent-based adhesive composition are disclosed, the compositions comprising (A) a polyester-urethane resin, (B) a phosphate ester compound, and (C) an aliphatic isocyanate curing agent. Methods for preparing a solvent-based adhesive composition, the methods comprising providing a polyester-urethane resin, providing a phosphate ester compound, mixing the polyester-urethane resin and phosphate ester compound to form a resin mixture, diluting the resin mixture in a solvent to form a diluted resin mixture having an application solid content of from 25 to 55 weight percent, based on the total weight of the diluted resin mixture, and curing the diluted resin mixture with an aliphatic isocyanate curing agent at a mix ratio (parts by weight resin mixture before dilution : parts by weight aliphatic isocyanate curing agent) of from 100:1 to 100:12. Laminates prepared comprising the solvent-based adhesives and according to the disclosed methods are also disclosed.
