Abstract: A description is given of a method of making film laminates using a lamination adhesive comprising (a) at least one acrylic polymer A with anhydride groups which are reactive with primary or secondary amine groups; and (b) at least one compound B with at least two amine groups selected from primary and secondary amine groups. The acrylic polymer A has a molecular weight of from 3000 to 50000 and the lamination adhesive is free of organic solvents, free of water and free of compounds with isocyanate groups.
