Abstract
Multicolored tone paint compositions containing flat metallic particles are produced by subjecting an electrically conductive substrate coated with the paint composition, while wet, to ion current. The field caused by the corona current vertically orients the metallic particles in that portion of the paint subjected to the current while the metallic particles in the unexposed paint remain in horizontal orientation.
