Abstract
This invention relates to strongly adhering coating compositions comprising at least one copolymer or cooligomer as an adhesion promoter, which copolymer or cooligomer comprises monomer units derived from at least one monomer selected from the group consisting of the acrylate and acrylamide monomers, at least one monomer selected from the group consisting of the amine containing ethylenically unsaturated monomers, at least one monomer selected from the group consisting of ethylenically unsaturated associative monomers and at least one monomer selected from the group consisting of the polyacrylates of polyols. The amine sites of the copolymers or cooligomers are at least partially neutralized with acid prior to film casting the coating formulation.
