  • 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
  • Publication number: 20070093639
    Abstract: The present invention relates to a supramolecular polymer comprising quadruple hydrogen bonding units within the polymer backbone, wherein at least a monomer comprising a 4H-unit is incorporated in the polymer backbone via at least two reactive groups up to four reactive groups, provided that the 4H-units are not covalently incorporated in the polymer backbone through one or more silicon-carbon bonds. The invention also relates to processes for preparing such supramolecular polymers and their use in personal care applications, surface coatings, imaging technologies, biomedical applications, (thermo)reversible coatings, adhesive and sealing compositions and as thickening agents, gelling agents and binders.

  • Publication number: 20060127637
    Abstract: The invention relates to a system for use in an electric or optical device comprising at least two organic or metallo-organic energy and/or charge variable moieties having conjugated unsaturated bonds, wherein at least one moiety has an energy state different from another of said moieties, characterized in that the system is a H-donor-Hacceptor system comprising at least one H-donor molecule having at least two hydrogen bonding clusters, each cluster comprising at least two groups having formed a hydrogen bond, and at least two H-acceptor molecules, each having at least one hydrogen bonding cluster, each cluster comprising at least two groups having formed a hydrogen bond with the groups of the H-donor molecule, at least one of the H-donor and H-acceptor molecules 10 further comprising one or more of the organic or metallo-organic energy and/or charge variable moieties.

  • 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.

  • Publication number: 20060018856
    Abstract: The invention relates to the synthesis of siloxane polymers containing self-complementary quadruple hydrogen bonding groups (4H-units). The resulting polymers show unique new characteristics that result from the reversible, physical interactions between the polysiloxane chains that are based on the (supramolecular) interactions between the 4H-units. The polysiloxanes in this invention show unprecedented bulk material properties and are used as gelling agents for silicone fluids. The resulting gels are clear and display good material properties, while having unparalleled high silicone fluid contents.
