Title:
ALUMINUM PIGMENT, METHOD FOR PRODUCING ALUMINUM PIGMENT, COATING MATERIAL COMPOSITION CONTAINING ALUMINUM PIGMENT, AND INK COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/038009
Kind Code:
A1
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.
