  • Ink composition
    Patent number: 10472531
    Abstract: The present disclosure relates to an ink composition containing a colorant; a hydroxylated co-solvent; a non-hydroxylated co-solvent, a polyurethane binder and water. The weight percent ratio of the hydroxylated co-solvent to the non-hydroxylated co-solvent in the ink composition ranges from 55:45 to 65:35; and the total amount of hydroxylated co-solvent and non-hydroxylated co-solvent in the ink composition is at least 18 wt %. The amount of polyurethane binder in the ink composition is 0.1 to less than 1 wt %.
    Type: Grant
    Filed: July 20, 2015
    Date of Patent: November 12, 2019
    Assignee: Hewlett-Packard Development Company, L.P.
    Inventors: Linda Sherry, Niamh Kelly, Richard J. McManus, Kevin Rattigan, John Breen
  • Magenta inks
    Patent number: 10414930
    Abstract: The present disclosure relates to magenta inkjet inks having a quinacridone pigment and an azo pigment. The azo pigment has at least one azo compound having the formula (I), in which Ra is selected from H, aryl and C1 to C4 alkyl, and Rb, Rc and Rd are each independently selected from H, a C1 to C4 alkyl, an oxygen-containing, a nitrogen-containing and a sulphur-containing functional group. Where Ra is aryl, the aryl is not a phenyl group having at least one hydrogen atom that has been substituted with a chlorine atom.

  • Treatment of endotoxin-associated disorders with cationic peptides
    Patent number: 5789377
    Abstract: A method for the microbial production of a cationic peptide having anti-microbial activity is provided, wherein the cationic peptide is first produced as a fusion protein having an anionic portion for suppressing the antimicrobial activity of the cationic portion. A novel cationic peptide having anti-microbial activity and LPS-binding activity is also provided. Such peptides are useful for suppressing the growth of bacteria and for the treatment of endotoxemia-associated disorders.
