Abstract
An aluminum pigment including plane particles having a particle planarity (shortest length/particle cross-sectional length) of 0.95 to 1.00 at 60% to 100% by number, wherein the mean particle diameter d50 of the particles is 4 μm to 15 μm. The inventive aluminum pigment is excellent in terms of optical properties, wherein the aluminum pigment can satisfy all of high denseness, high brightness in the regular reflection region, and low generation of scattered light.
