N-alkoxymethyl (meth)acrylamide functional polymers and their use in self-crosslinkable coating compositions |
摘要 |
Self-crosslinkable film-forming compositions and a process for preparing multi-layered coated articles coated with a pigmented or colored base coat and a transparent or clear topcoat containing a self-crosslinkable film-forming composition are disclosed. The self-crosslinkable film-forming composition comprises a non-gelled addition polymer which is the free radical initiated reaction product of an N-alkoxymethyl(meth)acrylamide and at least one other ethylenically unsaturated monomer. The topcoat composition may be aqueous based. The transparent topcoat provides a composite coating with improved acid etch resistance and mar resistance, making the composite coating particularly useful as a topcoat for automotive parts.
