  • Patent number: 10414154
    Abstract: In an example implementation, an image transfer method includes inkjet printing a latex ink image onto a propylene-ethylene copolymer film extruded onto a single-layer image transfer sheet. The method includes putting the latex ink image and the single-layer image transfer sheet in contact with a substrate, and using heat and pressure to exclusively transfer the latex ink image onto the substrate, after which the single-layer transfer sheet is removed from the substrate.
    Type: Grant
    Filed: March 18, 2016
    Date of Patent: September 17, 2019
    Assignee: Hewlett-Packard Development Company, L.P.

  • Patent number: 7401911
    Abstract: An apparatus and method of thermal inkjet printing is provided. The apparatus is adapted to be used with an inkjet ink including a pigment(s), an aqueous vehicle, and a sufficient amount of polymeric binder and/or humectant(s) to wet and directly adhere to non-porous, uncoated, untreated, hydrophobic media. The ink is adapted to be ejected through a thermal inkjet head with consistent image quality and no kogation. The concentration of binder and/or humectant(s) raises the viscosity of the ink at room temperature. As such, the apparatus is adapted to lower the viscosity of the ink prior to the ink being ejected through the thermal inkjet printhead. Additionally, the apparatus is adapted to prepare the media for receiving the ink, and dry the ink after the ink is deposited on the media. This can be accomplished by providing heat to the media and/or the ink during the printing process.

  • Patent number: 5699182
    Abstract: The present invention provides for light fatigue resistant photochromic compositions including a unique combination of hindered aminoether light stabilizer ("HAELS") compounds to extend the usable lifetime of naphthopyran photochromic compositions and articles. Additionally, light stabilizer compounds and hydroxyphenyl benzotriazole UV absorbers have a synergistic effect in extending the usable lifetime of photochromic compositions and articles. Specifically, certain tertiary and secondary amine HALS compounds in combination with hydroxyphenyl benzotriazole UV absorbers extend the usable lifetime of spiro-indolino-oxazine photochromic compositions and articles. Similarly, aminoether HAELS compounds in combination with hydroxyphenyl benzotriazole UV absorbers further extend the usable lifetime of the naphthopyran photochromic compositions and articles.
