Title: Aluminum pigment and production thereof
Inventor: SATO MASANORI
IPC: C09C1/64
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To obtain a pigment which realizes metallic appearance and interference color simultaneously and enables noncloudy bright color development and workability improvement in coating material preparation by forming an anodic oxidation film or an electrolytically colored anodic oxidation film on the surfaces of aluminum particles. SOLUTION: Aluminum foil having a thickness of 1-100 μm is subjected to anodic oxidation to form an anodic oxidation film having a thickness of 2 μm or lower, if necessary subjected to electrolytic coloration, then ground, and classified so that particles having particle sizes of 5-300 μm, thicknesses of 1-100 μm and particle sizes larger than thicknesses are obtd., thus giving an aluminum pigment. Light reflected at the surface of the anodic oxidation film interferes with light reflected at the surface of the aluminum substrate, enabling the development of color from brown to red dependently on the optical path difference. Since the optical path difference is determined by the thickness of the anodic oxidation film and the visual angle, the interference color can be controlled by changing the thickness of the oxidation film.
