  • Patent number: 6203736
    Abstract: The invention relates to platelet-shaped interference pigments for effect paints for painting objects of daily use, especially vehicle bodies, with the interference pigments including liquid crystal polymers (LCP) with main and/or side groups—mesogens—which are arranged at least approximately chirally-nematically or the like. In order to be able to paint different colored backgrounds in a covering fashion using the transparent interference pigments, the interference pigments are built up in several layers and also have at least one and preferably two interfering layer(s) of liquid crystal polymers and even of a single, preferably centrally located, light-absorbent layer, with the light-absorbent layer absorbing at least a portion of the visible light spectrum. Advantageously the light-absorbent layer can absorb light in the entire visible light spectrum, in other words appear black.
