Abstract: The process for coating or printing substrates with a coating or printing agent is characterized by the application to the substrate of a polymerizable substance containing liquid crystal, polymerizable monomers which for coating carry at least two polymerizable groups and for printing carry at least one polymerizable group, followed by polymerization, wherein the coating or printing agent contains a1) a chiral liquid crystal monomer and b) a polymer binder and/or monomer compounds that can be converted into the polymer binder by polymerization or, in the case of dispersion coatings and printing inks, a dispersing aid d), or the coating or printing agent contains a2) an achiral liquid crystal monomer, b) a polymer binder and/or monomer compounds that can be converted into the polymer binder by polymerization or, in the case of dispersion coatings and printing inks, a dispersing aid d), and c) a chiral compound that is not a liquid crystal.

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).
