  • Self-assembling dyes
    Patent number: 7355044
    Abstract: A novel dye according to formula (I): capable of self-assembling thus forming supra-molecular structures. These self-assembling dyes may be advantageously used in an ink-jet ink for improving the stability of ink-jet ink images to light fading.
    Type: Grant
    Filed: May 12, 2004
    Date of Patent: April 8, 2008
    Assignee: Agfa-Gevaert N.V.
    Inventors: Luc Vanmaele, Johan Loccufier, Egbert Meijer, Henricus Janssen, Pieter Fransen
  • Ink composition containing a particular type of dye, and corresponding ink-jet printing process
    Patent number: 7025813
    Abstract: An ink composition is disclosed which contains at least one novel dye (CU)n(SAU)m that is capable of self-assembling under appropriate conditions to form supramolecular structures. More than one novel dye (CU)n(SAU)m and/or at least one non-colored self-assembling compound (SAU?)p(X)q may be incorporated in these supramolecular structures. Also disclosed is an ink-jet printing process using these novel dyes, and an ink-jet printing apparatus provided with an ink cartridge containing such a dye.

  • Ink composition containing a particular type of dye, and corresponding ink jet printing process
    Publication number: 20030209166
    Abstract: An ink composition is disclosed which contains a novel type of dye (DYE)n(SAU)m that is capable of self-assembling under appropriate conditions, or is capable of assembling with another analogous dye (DYE′)n′(SAU′)m′, or is capable of assembling with a compound (SAU″)p(X)q, thus forming supramolecular structures. Also disclosed is an ink jet printing process using these novel dyes, and an ink jet printing apparatus provided with an ink cartridge containing such a dye.
