Abstract
A pigment comprises a substrate, a metallic layer formed on at least one surface of the substrate and imparting metallic luster, and a transparent inorganic compound layer formed on surfaces of the substrate and the metallic layer. Thereby, the pigment produces color by light interference of a ray reflected on a surface of the transparent inorganic compound layer and a ray passed through the transparent inorganic compound layer and reflected on a surface of the metallic layer. Thus, the pigment is excellent in coloring power and hiding power, and particularly useful for an automotive finishing paint.
