Laminates of polymeric films and solvent-based polyurethane adhesive formulations for preparing them are provided. The adhesive formulations include a hydroxyl-terminated polyester that forms crystalline polyester domains after reaction with an appropriate polyisocyanate, but prior to completion of cure. The result is an adhesive layer that substantially enhances the oxygen barrier properties of the adhesive and, therefore, of the laminate as a whole, while offering desirable convenience of application even at relatively low temperatures. The laminates may also exhibit desirable retention of barrier properties following flex-cracking.

Method of making laminates having reduced oxygen permeability

A coating composition comprising: an aqueous dispersion comprising: the melt-kneading product of (A) a base polymer which comprises one or more thermoplastic polymers, (B) a stabilizing agent which comprises at least one component selected from the group consisting of acrylic acid grafted ethylene-based polymers and maleic anhydride grafted polyolefins; (C) a neutralizing agent; and (D) water; wherein the aqueous dispersion has a volume average particle size of less than about 5 &#x3bc;m is provided.
