    Abstract: The present disclosure provides multicoat systems exhibiting ultraviolet (UV) stability after ultraviolet exposure and moisture exposure. The systems comprise at least one primer (G), at least one pigmented coating (P) disposed on a surface of the primer, and at least one ultraviolet (UV) absorber which has an absorption maximum of at least 370 nm. The pigmented coating (P) may be comprised of two or more coatings (P1), (P2) to (Pn). The multicoat systems may also comprise a transparent coating material (T) to form a transparent coating (K). The present multicoat systems demonstrate ultraviolet stability, reduced delamination of the pigmented coat from the primer and are available in a variety of shades for use in the finishing, refinishing and coating of component parts. The present disclosure also provides for a process for producing the multicoat system, and provides for the use of the system.
