Patents by Inventor Mathew Mathew

Mathew Mathew has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10845924
    Abstract: Described herein are capacitive devices and methods for producing same using printing methods such as flexography, gravure, offset, lithography, etc. The capacitive devices are formed from printing conductive inks, non-conductive inks, masking ink layers, graphic artwork layers, and overprint layers on a substrate. Interaction between a conductive ink layer of the capacitive device with a touch screen device of a computer, tablet, smart phone, etc. causes a capacitive effect that allows information coded in capacitive device to be read, leading to an activity such as the download of content to the device having the touch screen.
    Type: Grant

  • Publication number: 20200339838
    Abstract: Described herein is an actinically curable adhesive composition, suitable for sealing flexible packaging, that includes an inert urethane polymer and an ethylenically unsaturated monomer component selected from at least one monofunctional ethylenically unsaturated monomer, at least one multifunctional ethylenically unsaturated monomer, and a combination thereof, wherein the ethylenically unsaturated monomer component disperses the inert urethane polymer. The compositions are suitable for forming flexible packaging materials for foods and other materials, particularly sensitive materials. Also described are flexible packaging materials and a method for preparing an actinically curable adhesive composition.

  • Patent number: 9080067
    Abstract: A method of formulating ink for high-speeding printing includes controlling a surface tension of the ink to equal to or greater than 26 mN/m, equal to or greater than 28 mN/m, or equal to or greater than 30 mN/m. The surface tension is measured when the ratio of the total non-volatiles volume fraction of the ink to the maximum total non-volatiles volume fraction of the ink is a ratio between about 0.40 and about 0.90. An ink for high-speed printing includes one or more resins, one or more colorants, one or more solvents, and one or more additives. The ink can be a flexographic ink, a rotogravure ink, a heatset offset ink, or a publication gravure ink. A print of the ink includes less than 1% of pinholes by area. A method of printing includes preparing an ink and applying the ink to a substrate. The ink has a surface tension of equal to or greater than 26 mN/m, and the substrate moves at a speed of greater than 1200 feet/min.
