Latest Patents
One of his latest patents is for a prismatic retroreflective article and method. This innovative article features a transparent body portion and a layer of internally reflecting cube-corner optical elements. These elements have an open air-exposed rear surface that is designed to be more hydrophobic, more oleophobic, or both compared to the underlying cube-corner optical element. The manufacturing process involves treating or coating portions of the cube-corner elements to achieve these properties while leaving them exposed to the open air.
Another significant patent involves retroreflective articles that utilize multilayer films. These articles are particularly useful for commercial graphics and retroreflective products, such as roll-up signs for highway transportation safety. The multilayer films consist of at least one layer of polyurethane and at least one layer of a copolymer of alkylene and a non-acidic, polar co-monomer. This innovation not only provides the same or improved performance but also reduces costs and enhances manufacturing methods compared to previous articles.
