Abstract
The present invention relates to pigment and coating compositions that are used to prepare pigmented coatings that exhibit geometric metamerism or metallic flop. The pigment compositions comprise a small particle size pigment and a flop-enhancing agent, which flop-enhancing agent is a copper phthalocyanine, an indanthrone or a carbazole dioxazine compound. A method of enhancing the flop of a pigmented polymeric coating by incorporating one or more flop-enhancing agents into the composition is also disclosed.
