A primer and a substrate comprising a polymer comprising a copolymer unit of an ultraviolet absorber having an unsaturated double bond are described, and a multilayer coating comprising the coating and the surface coating of the primer. Coatings of multilayer coatings exhibit excellent weathering adhesion to the substrate and improve their surface properties such as surface hardness, scratch resistance, abrasion resistance and surface gloss. Thus, the coating imparts excellent durability to the coating and suppresses the deterioration of the substrate due to gas phase change. |
