摘要:
The invention relates to a pigment with color dependent on the viewing angle, which has been obtained by three-dimensional crosslinking of oriented substances of liquid-crystalline structure having a chiral phase. In order to stabilize the color of such a pigment at elevated temperatures, crosslinking is carried out in the presence of at least one additional, color-neutral compound comprising at least two crosslinkable double bonds.
