摘要
The invention relates to colorant compositions consisting essentially of one or more cholesteric liquid-crystalline polymers and at least one colorant which absorbs light in the visible wavelength range. Suitable colorants are organic or inorganic pigments or dyes. Coatings comprising such colorant compositions feature color effects which are dependent on the viewing angle and which cannot be obtained by means of absorption pigments alone or by means of cLCP effect coatings.
