Latest Patents

One of his latest patents is titled "Imaged articles comprising a substrate having a primed surface." This invention relates to an imaged article that includes a substrate with a primed surface layer. The primed surface layer is made from a base polymer that possesses specific solubility parameters, molecular weight (Mw), and glass transition temperature. The primer enhances overall image quality by improving properties such as ink uptake, dot gain, color density, and ink adhesion. The preferred primer compositions are partially soluble in the ink composition, which increases ink layer thickness and enhances durability and day/night color balance. Various substrates can be primed, including sheeting for traffic control signage and commercial graphic films for advertising.

Another significant patent is the "Ink jet receptive coating." This invention involves articles that consist of a substrate with an ink receptive layer and an ink-jet printed image, along with methods for ink jet printing. The ink receptive layer is composed of specific urethane-containing polymers and blends, which contribute to the quality of the printed images.
