  • Toner particles comprising a thermosublimable dye or pigment for use in sublimation transfer textile printing are quite well known in the art.
  • the process for textile printing proceeds as follows.
  • a toner image is formed on an intermediate substrate (e.g. paper, plastic sheet, etc.), the intermediate substrate carrying the toner image is contacted with textile and is heated for a (short) period of time.
  • the sublimable dye or pigment evaporates and enters the textile to be printed where the dye or pigment molecules diffuse into the fibre.
  • the intermediate substrate carrying the toner image is removed.
  • This system is especially well suited for printing on synthetic fibres, e.g. polyester.
  • spherical magnetic toner particles are prepared from a magnetic product, a polymer, and a wax.
  • the dye used sublimates at 100-200 °C and the wax is preferably a montana wax.
  • a dry electrophotographic developer consisting of a single type of particles containing an electrically conductive substance, a magnetic substance and a binder.
  • the developer contains Carbon black (2-20%), dye(s) 5 subliming or vaporising at 130-240 degrees C a wax and a plasticiser.
