ABSTRACT:
Flexible laminates are prepared using a room temperature curable, water-borne laminating adhesive. The adhesive consists essentially of a copolymer emulsion of an alkyl acrylate, alkyl methacrylate, styrene or vinyl ester, or mixtures thereof, and an ethylenically unsaturated carboxylic acid, and optional selected comonomers, combined with an epoxy resin emulsion and a polyfunctional amine. The flexible laminates are characterized by rapid room temperature curing, high bond strength, superior heat resistance and chemical and water resistance.
