    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.
