Latest Patents

One of McMullen's latest patents is for a multilayer graphic article with a color layer. This invention comprises a substrate, at least one color layer disposed on the substrate, and a protective surface layer that overlies both the substrate and the color layer. The color layer is visible through the surface layer and includes a color agent in a copolymeric binder. The binder is the copolymerization product of an olefinic monomer and a second monomer with a pendant carboxyl group. The substrate can be a polymeric film, an adhesive, or a temporary, removable liner. The protective surface layer can be formulated to provide interior surface protection or to make the graphic article weatherable and resistant to chemical exposure.

Another notable patent by McMullen is for an embossed multilayer film. This film consists of an embossed base layer and a conformable, uniformly thick protective surface layer that covers the base layer. In one embodiment, the embossed multilayer film can be re-embossed. In another embodiment, the surface layer is made from a polyurethane-based material. This invention also includes a method for producing such an embossed multilayer film.
