The invention discloses a solvent-based adhesive composition including (A) a polyester-urethane resin, (B) a phosphate compound, and (C) an aliphatic isocyanate curing agent. A method for preparing a solvent-based adhesive composition, the method comprising providing a polyester-urethane resin, providing a phosphate compound, and mixing the polyester-urethane resin and the phosphate compound to Forming a resin mixture, diluting the resin mixture in a solvent to form a diluted resin mixture having an applied solids content of 25 to 55 weight percent based on the total weight of the diluted resin mixture, and 100: 1 to The mixing ratio of 100: 12 (parts by weight of the resin mixture before dilution: parts by weight of the aliphatic isocyanate curing agent) the diluted resin mixture was cured with an aliphatic isocyanate curing agent. A layered article comprising the solvent-based adhesive and prepared according to the disclosed method is also disclosed. |
