PIGMENT THAT EXHIBITS POLYCHROISM DEPENDING ON VISUAL ANGLE,ITS PREPARATION, COMPOSITION CONTAINING THE PIGMENT, COATING MATERIAL, PLASTIC, RAW MATERIAL FOR FIBER, PRINTING INK OR COSMETIC PREPARATION CONTAINING THE PIGMENT, AND SAFETY SIGN

摘要

These pigments are characterised in that they comprise oriented, three-dimensionally crosslinked substances having a liquid-crystalline structure with a chiral phase and optionally further dyes and pigments, where the further dyes and pigments optionally present do not serve as support for the oriented, three-dimensionally crosslinked, liquid-crystalline substances with a chiral phase.
