FIELD: laminating adhesives.
SUBSTANCE: invention relates to laminating adhesives used in production of flexible laminates. Laminating adhesive composition contains an aqueous dispersion of thermoplastic polymer particles impregnated with an epoxy compound, and at least one water-emulsifiable or water-dispersible epoxy curing agent. Thermoplastic polymer particles are acrylate particles. Epoxy compound is an aliphatic epoxy resin or cycloaliphatic epoxy resin. Concentration of the epoxide compound is 1–40 wt % with respect to the total weight of the solid substance in the aqueous dispersion. Epoxy curing agent is selected from polyamines, polyamides, amidoamines, carboxyl functional polyesters, anhydrides, mercaptans, polymercaptans, cyclic amidines and their combination.
EFFECT: higher adhesion strength.
