摘要： A mixture of crosslinkable liquid-crystalline substances having a chiral phase (LC mixture), containing polymerizable groups, where at least 90% of the polymerizable groups are part of molecules containing at least two polymerizable groups (crosslinker molecules), wherein from 3.2 to 15 mmol of polymerizable groups are present per g of LC mixture. The crosslinked pigments show little color shift in the presence of solvents or upon application to substrate different temperatures.

摘要： The invention relates to mixtures containing pigments which comprise oriented three-dimensionally crosslinked substances having a liquid-crystalline structure with a chiral phase, and to the use of such mixtures. Pigment and matrix are matched to one another in such a way that on application of the mixture at different temperatures to a substrate, the lowest application temperature and highest application temperature differing by at least 10° C. and by not more than 150° C., there are no visually perceptible color differences of the pigmented paint on the substrate after drying.
