摘要:
The present invention discloses coated objects, such as car bodies, as well as coatings for coating such objects. In order to achieve new, hitherto unknown color effects with said coatings, at least some, and preferably only platelet-like interference pigments are mixed into the coating. When the coating is applied, the interference pigments automatically align themselves in a direction approximately parallel to the object surface. These interference pigments are made of liquid crystalline side chain polymers with a nematic and a chiral component, in which the side group mesogens are at least approximately nematic, smectic and/or cholesteric. Particularly intensive tones having a hitherto unknown brilliance may thus be obtained on a coated object, or a shimmering effect depending on the angle of incidence of light and viewing direction.
