Abstract
The invention relates to the use of copolymers which as well as other monomers contain in copolymerized form 10% to 90% by weight of monomers containing heterocyclic basic groups, and which do not contain vinylpyrrolidone as a monomer component, as additives in paints for improving the adhesion of the solid paint film to a substrate.The invention also relates to cured and uncured polymer compositions comprising copolymers which as well as other monomers contain in copolymerized form 10% to 90% by weight of monomers containing heterocyclic basic groups, and which do not contain vinylpyrrolidone as a monomer component, as adhesion improver additions.
