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).
