Claims20
A primer, comprising a film-forming dispersion or solution, comprising:
- an A polymer, which comprises a polyolefin or a polyolefin mixture;
- a B polymer, which comprises at least one member selected from the group consisting of a (meth)acrylate homopolymer and a (meth)acrylate copolymer, comprising at least one member selected from the group consisting of a standard methacrylate and a standard acrylate;
- and
- an AB polymer, which comprises a graft copolymer comprising the A polymer and the B polymer,
- wherein the film-forming dispersion or solution is halogen-free and acid-free;
- and
- wherein the primer is suitable for coating at least one polyolefin,
- wherein the B polymer and the AB polymer have silyl groups,
- wherein the AB polymer is a graft copolymer comprising a polyolefin main chain and at least one poly(meth)acrylate side chain.
