Abstract

A laminating and coating adhesive based on an aqueous dispersion of PA1 (1) a copolymer of a vinyl ester, and/or an acrylic acid ester, and/or a further monomer and an ethylenically-unsaturated functional group-containing monomer having from 3 to 18 carbon atoms and hydroxy and carbonyl groups as functional groups, such as a monocarboxylic acid or dicarboxylic acid and/or N-methylol-(meth)-acrylamide, PA1 (2) an epoxy compound, and PA1 (3) an amine hardener. The adhesive gives a laminate bond with especially high resistance to peeling even in the case of thermal stress and/or in the presence of water.
