摘要：
A process for preparing an effect coating having a perceived color which is dependent on the viewing angle, which comprises applying one or more non-curable cholesteric liquid-crystalline polymers, or at least one non-curable nematic liquid-crystalline polymer and at least one non-curable cholesteric liquid-crystalline polymer, in the form of a melt or in solution, to the article that is to be coated, and converting the applied polymer by temperature treatment into a film having a perceived color which is dependent on the viewing angle.
