ABSTRACT:
The invention relates to pigments whose color depends on the viewing angle, their preparation and use.
These pigments comprise oriented three-dimensionally crosslinked substances of liquid-crystalline structure having a chiral phase and, if desired, further dyes and pigments, the further dyes and pigments if present not serving as base for the oriented three-dimensionally crosslinked liquid-crystalline substances having a chiral phase.
