Abstract

Pearlescent coatings have been widely used in various industrial products such as automotive paints and plastics coatings since it generates special visual appearance called the angle-dependent color shift effect. Curved objects painted with these coatings would be viewed and illuminated from many different directions, and this feature makes the visual appearance change according to different view and light directions. Pearlescent coatings are composed of four layers including clearcoat, platelet coat, black base coat and substrate. Among four layers, the color shift occurs by the platelet coat layer.
