Angle-Dependent Color (Color Travel): Many types (like color-shift or interference pigments) change color depending on the viewing angle and light source, creating a dynamic visual experience.
Luster and Reflection: They manipulate light through reflection, refraction, and interference. This creates effects ranging from a soft, metallic sheen to a brilliant, glittering sparkle.
Depth and Dimension: Unlike flat, solid colors, they give surfaces a sense of depth and three-dimensionality, often making the coating appear liquid or multi-layered.
Complex Composition: They are often multi-layer structures, typically based on substrates like mica, glass, or aluminum flakes, coated with thin films of metal oxides.
Versatile Applications: Widely used in high-end automotive paints, cosmetics, printing, and security features (like on banknotes) to provide distinctive, hard-to-copy finishes.
