Abstract
Abstract A multilayer graphic article comprises a substrate, at least one color layer disposed on the substrate, and a protective surface layer that overlies the substrate and the color layer. The color layer is visible through the surface layer and comprises a color agent in a copolymeric binder. The binder comprises the copolymerization product of an olefinic monomer and a second monomer having a pendant carboxyl group. The substrate may be a polymeric film, an adhesive or a temporary, removable liner. The protective surface layer may be formulated to impart interior surface protection properties to the graphic article or it may be formulated to render the graphic article weatherable and resistant to chemical exposure.
