  • MONODISPERSE PARTICLES
    Publication number: 20100239620
    Abstract: The present invention relates to novel monodisperse particles, which comprise at least one broad spectrum absorber contrast agent and/or at least one precursor of a broad spectrum absorber contrast agent, which is encapsulated in the monodisperse particle, novel colourant compositions, to uses thereof in colouring a substrate and to substrates that are coloured (at least in part) using the colourant compositions.
    Type: Application
    Filed: May 13, 2008
    Publication date: September 23, 2010
    Inventors: Michael Francis Butler, Ramin Djalali
  • Dyeing and/or Printing Formulations Comprising Monodisperse Particles
    Publication number: 20100040741
    Abstract: The present invention relates to a printing formulation comprising monodisperse particles, at least one curing agent, at least one initiator and a solvent, as well as to the use of these formulations and to substances printed with these formulations.
    Type: Application

  • Colourant Compositions and Their Use
    Publication number: 20090047352
    Abstract: A fibre colourant and an ink composition are provided which comprise monodisperse particles capable of forming a colloidal crystal that diffracts light having a wavelength in a range that corresponds to the wavelength of visible light. The use of such compositions in colouring substrates is also provided.
