  • Radiation curable solid ink compositions suitable for transfuse printing applications
    Patent number: 8449095
    Abstract: This disclosure is generally directed to curable solid inks, such as radiation-curable solid inks, and their use in forming images, such as through transfuse printing. More specifically, this disclosure is directed to radiation-curable solid inks, such as ultraviolet-light-curable phase-change inks, that comprise curable and non-curable waxes.
    Type: Grant
    Filed: July 13, 2010
    Date of Patent: May 28, 2013
    Assignee: Xerox Corporation
    Inventors: Marcel P. Breton, Michelle N. Chretien, Christopher A. Wagner, Ian R. Duffy, Peter G. Odell
  • Curable solid ink compositions
    Patent number: 8236870
    Abstract: A curable solid ink composition including a curable component, a non-curable component including an ethoxylated octylphenol derivative, a photoinitiator, and a colorant. The curable solid ink composition has a viscosity in the range of less than 10 cPs at 90° C., a shrinkage value of less than 3%, and a superior curing rate compared to existing curable solid ink compositions. The ethoxylated octylphenol derivatives may be prepared by reacting an ethoxylated octylphenol, a linear alcohol, and diisocyanates or polyisocyanates.
