ANIONIC ELECTRODEPOSITION COATING MATERIAL AND COLORED ALUMINUM MATERIAL OBTAINED BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a coating material capable of providing a colored aluminum material having an excellent finish by making the coating material including a specific organopolymer. SOLUTION: This anionic electrodeposition coating material contains a hollow organopolymer having 0.01μm to 1μm average particle diameter, 0.005μm to 0.5μm average inner particle diameter and 0.01-0.9 ratio of the inner particle diameter/the particle diameter in an anionic electrodeposition coating material containing a melamine curing type acrylic resin as a curable resin component. A coating film obtained from the coating material has opacifying properties.
