METHOD OF FORMING LAYERED COATING FILM

摘要

A method of forming a layered coating film includes: coating a workpiece with an electrodeposition coating material to form an electrodeposition coating layer; applying a colored coating material including a white pigment over the electrodeposition coating layer to form two or more colored coating layers that are layered on the electrodeposition layer; and applying a clear coating material over the two or more colored coating layers. The colored coating material includes coating materials respectively applied to form a lower-side colored coating layer and an upper-side colored coating layer of the two or more colored coating layers. A concentration of the white pigment in the coating material applied to form the lower-side colored coating layer is equal to or higher than a concentration of the white pigment included in the coating material applied to form the upper-side colored coating layer.
