A solvent-based adhesive composition is disclosed that includes (A) a polyester-urethane resin, (B) an epoxy-terminated polyester compound, (C) phosphoric acid, and (D) an aliphatic isocyanate. Hardener. A method for preparing a solvent-based adhesive composition, the method comprising providing a polyester-urethane resin, providing an epoxy-terminated polyester compound, and mixing the polyester-urethane resin , Epoxy-terminated polyester compound and phosphoric acid to form a resin mixture, dilute the resin mixture in a solvent to form a diluted resin mixture, and based on the total weight of the diluted resin mixture, the diluted resin mixture The applied solid content is 25 to 55 weight percent, and the aliphatic isocyanate curing agent is used to cure the substrate at a mixing ratio of 100: 1 to 100: 12 (parts by weight of the resin mixture before dilution: parts by weight of the aliphatic isocyanate curing agent). Dilute the resin mixture. A layered article comprising the solvent-based adhesive and prepared according to the disclosed method is also disclosed. |
