ABSTRACT:
Improved bonded properties of dry-laminated flexible film substrates, for instance laminates comprising films of thermoplastics such as polyolefins, polyesters, and polyamides, as well as paper, cellophane, and metals, particularly after exposure to boiling water, are obtained with polyurethane dispersion adhesives when a plural aziridine or carbodiimide compound, or a mixture of a plural epoxy compound with a plural aziridine or carbodiimide compound, is employed as the crosslinker for the adhesive system.
