Abstract
Provided is an aluminum pigment which is excellent in terms of a sense of compactness, optical characteristics, and dispersion/workability, and which can realize a metallic design. In this aluminum pigment, metallic aluminum particles have an average thickness of 0.02-0.20 μm, an average aspect ratio (particle cross section length/particle cross section thickness) of 40-100, and a standard deviation of aspect ratio of 15-70.
