Abstract: A process is disclosed for producing pigment particles and is characterised in that: either a polymerisable mixture containing a dye or interference colouring agent is applied to a surface with recesses in the shape of the desired pigment particles, and is then polymerised, the polymerised pigment particles being afterwards removed from the recesses; or said polymerisable mixture is applied to a smooth surface in the shape of the desired pigment particles, the shape being set in the known way by a printing process, and then polymerised, the polymerised pigment particles being subsequently removed from the surface (not including the production by offset printing of pigment particles of cholesteric-liquid crystalline structure).

Abstract: A novel carrier which is stable and effective over long cycle times (6 x 105 prints), has an iron oxide coating of the formula (FeO)x . Fe2O3 where x = 0.1 - 1 and is obtained by treating steel cores (or balls) with defined small amounts of sulfuric acid of defined concentration, partial oxidation of the cores thus treated and drying at 60-150.degree.C at ? 100 mbar.
